Multiple myeloma is a bone marrow-based plasma cell tumour that develops from asymptomatic pre-cursor conditions smouldering myeloma and monoclonal gammopathy of uncertain significance and all are characterised by the presence of a monoclonal protein in the blood. Diagnosis and distinction between these conditions is based on blood tests, the bone marrow biopsy and cross sectional imaging. There are various risk stratification models that group patients with smouldering myeloma into risk groups based on risk of progression to symptomatic disease. Management is mainly observational for patients with smouldering myeloma although clinical trials for high-risk disease may be available. Restaging is required if evidence for progression., (© 2024 British Society for Haematology and John Wiley & Sons Ltd.)

Significant efforts have been made over the past decade to facilitate the recognition of environmentally friendly packaging and promote sustainability. Yet, consumers remain confused by the excess of labels and claims used to communicate sustainability. In our previous work, we modified the appearance of recycled fibre‐based packaging by incorporating visible particles of fibre‐based waste. This strategy enabled consumers to better identify packages with a high recyclability level, enhancing their environmental perception towards sustainable products. However, the incorporation of such large waste particles proved to be detrimental to the mechanical properties of the paperboards. In this study, we further investigate the influence of the physicochemical properties of the added fibre‐based waste on packaging performance. Using a similar strategy to enhance the environmental perception, we herein studied the effect of mixed office waste (MOW), old magazines (OMG), and polylactic acid (PLA) paper cups. The presence of hydrophobic and difficult‐to‐process and difficult‐to‐disperse waste, such as the PLA paper cups, significantly altered the mechanical performance of the paperboards, whereas more hydrophilic and easy‐to‐disintegrate waste (MOW and OMG) had a lesser effect regardless of the size of the particles. Strength agents such as cationic starch (CS) and cellulose microfibrils (CMFs) successfully restored the properties of the paperboards containing MOW and OMG but were less effective for PLA paper cups. A multi‐ply strategy overcame the limitations of CS and CMFs using the redesigned paperboard as an outer ply for aesthetic purposes and a 100% recycled inner ply for restoring strength.

Paper and paper board are an ideal choice of packaging material due to their biodegradability. They are safer than commonly used plastic packaging materials. But due to the presence of carbon sources like cellulose and starch in paper, various pathogenic and non‐pathogenic microbes can grow well in them. The migration of microorganisms or their spores from paper to food may cause serious health hazards. Taking consumer concerns into picture, the regulatory authorities should come up for food packaging standards with regard to microbial limits of paper used in food packaging. This study pinpoints the correct approach, that is, the disintegration method in comparison to direct plating in evaluating the microbial load of 14 different samples of paper by demonstrating the limitations of methods that were eliminated. The samples were also tested for storage effect on microbial load and found to have significant reduction in bacterial load during storage at 4°C, but for fungi, it remained nearly unchanged. Further identification of predominating microbes was performed, and conclusions have been drawn on the presence of harmful and harmless species in the samples of paper. It was found that all the identified fungi are mycotoxin producing and may lead to illness of the consumer. Unlike fungi, dominating bacterial strains were found to be non‐harmful for food packaging purposes and ultimately for human use. Overall, there is an immediate need to set microbial limit standards in food packaging paper and paperboard in order to supply safe and hygiene food to consumers. [ABSTRACT FROM AUTHOR]

Chicken meat is well known for its high nutritional value. Its shelf life is short, due to the pronounced perishability, even under refrigeration. Paper bags are usually used as packaging materials, due to their biodegradability. The main negative aspect concerning paper is its high porosity and low moisture barrier. In this regard, it has to be coated/modified with efficient moisture barrier materials. The storage of chicken breast meat wrapped in four types of paper‐based materials currently in use in Romania (RO), Italy (IT), Spain (SP) and Slovenia (SLO) is reported. RO and IT are paper coated with polyethylene (PE) film, SP is waxed paper, and SLO is paper modified with hydrophobized starch. The influence of the coating film on the organoleptical, biochemical and microbiological characteristics of the chicken breast meat stored at 4°C was the aim of the study. The mathematical modelling revealed two aspects: (1) the stability period in which the meat safe for consumption is in the range 1.92–2.18 days in the case of all paper types, and (2) cadaverine, the amine generated by protein degradation, is a less sensitive indicator of the meat alteration than microbial growth. The papers coated with PE (RO and IT samples) and with hydrophobized starch (SLO paper) were packaging materials more efficient that the waxed paper (SP sample). The polyethylene film reduced the conversion of putrescine into spermidine in a higher extent than wax. [ABSTRACT FROM AUTHOR]

Collation shrink film is often used for bundling single packages of consumer goods. Like other plastic films, this type of film is currently under social pressure. Paper could be an environmentally friendly alternative if a suitable type of paper can be applied in such a way that the requirements for manipulation and transport of the bundles are met. In this study, the use of paper for bundling bottles is experimentally investigated. The study focuses on bundles of six PET bottles of 1.5 L containing flat water and sparkling water. Suitability of a paper‐based bundling method is evaluated in terms of rigidity of the bundle and in terms of resistance to horizontal inertial forces that inevitably occur during transport. Behaviour of collation shrink film‐based bundles is taken as a minimum performance level. The study shows that various paper‐based bundling methods can technically qualify as a replacement for collation shrink film and even offer additional benefits. A particular promising concept consists of a band of paper that is stretched around the bottles. It allows lifting the bottles by grasping two caps only, and it beats shrink film regarding resistance to varying horizontal inertia forces. Further research is necessary to optimise the concept and to adopt it for a wider range of products and for industrial use. [ABSTRACT FROM AUTHOR]

Single use packaging is one of the major contributors to environmental issues linked to waste in the environment. Packaging materials often consist of several plastics, which, when combined, are difficult to recycle. One option to reduce these issues are packaging materials for which recycling infrastructure and end markets exist, such as paper. Use of paper in food packaging applications is limited due to poor barrier properties. Enhancing barrier properties without impacting recyclability can be achieved by thin polymeric coatings combined with vapour‐deposited aluminium. Water vapour transmission rate (WVTR) of packaging materials is often assessed at 38°C and 90% relative humidity (RH). These conditions, not experienced in the supply chain, may not be optimal for paper as they have the potential to alter the structure of paper by inducing expansion disrupting barrier. This study aims at verifying this hypothesis by evaluating the influence of temperature and RH on the measured WVTR of high barrier paper. Results show that testing such papers at 38°C and 90% RH yields WVTR approximately 10 times higher than when tested at 23°C and 85% RH. The link between this increase and the disruption of the barrier layer is demonstrated by testing samples preconditioned at 38°C and 90% RH and tested at 23°C and 85% RH, depicting an increased WVTR as well. Results suggest that integrity of barrier layer in paper was disrupted at 38°C and 90% RH, and hence, these conditions are deemed inappropriate for testing barrier performance of paper materials.

Active wrapping papers varied in bio-based coating materials (chitosan and carboxymethyl cellulose) and vanillin concentrations (0.5%, 1.0%, 2.0%, and 4.0% (w/v)) were prepared to study their antifungal effects and release properties. Chitosan-coated paper with 1% (w/v) vanillin gave the best inhibition against mycelial growth of mango anthracnose fungi and could inhibit its conidiospores germination. The release of vanillin from a chitosan-coated paper under different conditions of temperatures (13°C, 25°C, and 37°C), relative humidity (RH) (75%, 86%, and 96% RH), and pH values (pH 3.8, 5.2, and 6.2) was studied. Moreover, the vanillin release from the paper to mango fruit under an actual commercial storage condition (13°C, 90% RH) was also investigated. The predominant mechanism of vanillin release under low temperatures (13-25°C) and all RH studied was a Fickian diffusion, whereas the high temperature (37°C) and in all buffers varying pH showed a non-Fickian behaviour. Increasing temperature and RH enhanced in diffusion coefficient (D value) from 78.24 × 10-10 to 162.10 × 10-10 cm2/s and 42.87 × 10-10 to 59.98 × 10-10 cm2/s, respectively. Meanwhile, the increasing pH value reduced the D value from 233.87 × 10-10 to 122.74 × 10-10 cm2/s. The kinetic of vanillin release under an actual wrapping application exhibited a non-Fickian behaviour, and the D value was considerably low (approximately 65.36 × 10-12 cm2/s). The developed active wrapping paper can be great interest for food industry and is practically reasonable for postharvest mango fruits. [ABSTRACT FROM AUTHOR]

The presence of mineral oil saturated hydrocarbons (MOSH) and aromatic hydrocarbons (MOAH) in food is a safety concern. Migration to food from recycled paper and board is a relevant source of MOSH and MOAH, and the potential of several technologies to reduce it was explored. These technologies were assessed for food safety (people), environment (planet) and economy (profit) in an integrated way, using a framework developed to compare the effect of the technologies with the current state of the art. Two mature technologies were evaluated (MB12 and flotation), two in development (supercritical CO2 and thermal treatment), and two as a concept (anionic trash catchers and functionalized clays). The use of mineral‐oil‐free inks for printing newspapers was also evaluated. It was concluded that, although it is desirable to apply mineral‐oil‐free inks, in the short‐term reduction technologies have more impact. All technologies of which the effectiveness could be investigated (MB12, flotation, supercritical CO2 and thermal treatment) are able to reduce the potential migration of mineral oils by >70%, but none score optimally on all indicators. The MB12 technology shows the best overall performance and is ready for implementation, provided its patent will be available to more parties. Supercritical CO2 performs best on food safety, but environmental and economic performance has to be improved. The developed assessment framework yields a clear overview of the advantages and disadvantages of the technologies. Based on the assessment, recommendations are made to stakeholders, including the recycling industry, the ink and printing industry, the food industry and research institutes. [ABSTRACT FROM AUTHOR]

Ag@ceramic composite papermaking pigment was prepared by coating silver onto red ceramic powder using the electroless plating method. SEM and XRD showed that the ceramic pigments have a porous crystalline structure and that silver particles had been successfully loaded onto the surface and into the pores of the Ag@ceramic. Untreated ceramic pigment and Ag@ceramic pigment were incorporated into paper sheets by coating, filling and filling‐coating. Using spinach as an example, the ability of the different papers to preserve food was then evaluated. Four indicators were used to assess the preservative effect of the papers: inhibition of growth of Staphylococcus aureus and Escherichia coli, weight loss of the spinach and retention of vitamin C and chlorophyll in the spinach. Although the ceramic preservative paper has no antibacterial properties, it reduced weight loss from the spinach and increased retention of vitamin C and chlorophyll. The antibacterial preservative papers inhibited the growth of E. coli and S. aureus by >99%, and because of their additional antibacterial activity, these papers preserved the spinach more effectively. The experimental results showed that the antibacterial food‐preservative paper incorporating ceramic pigments had great potential in food packing applications. [ABSTRACT FROM AUTHOR]

This research focused on the enhancement of paper through the incorporation of a biodegradable and hydrophobic film coating with antioxidant properties. The effects of different lemongrass essential oil (LEO) concentrations (0–12%) on the physical, mechanical, microstructural, water‐resistance, antioxidant and biodegradable properties of gelatine/palm wax/lemongrass essential oil (GPL)‐coated paper were analysed. Uncoated paper was used as a control. The GPL‐coated papers were heat sealable and had significantly (p < 0.05) higher tensile strength and stretchability but lower stiffness than those of the control paper. The GPL‐coated paper incorporated with higher LEO concentrations showed a significant (p < 0.05) increase in the initial contact angle while also demonstrating significant (p < 0.05) reductions in the Cobb value and water vapour permeability. The GC–MS analysis revealed that LEO was highly dominated by monoterpenes, sesquiterpenes, and their oxygenated derivatives, supporting that all GPL‐coated papers have a good amount of total phenolic compounds and free radical scavenging activities, which improved significantly (p < 0.05) with higher LEO concentrations. In conclusion, the GPL film coating was capable of improving the physical, mechanical and functional properties of Kraft paper and has the potential to be applied for food products.

The migration model of contaminants from inks on paper packaging to food is developed based on the penetration of ink in paper and Fick's diffusion. The printed paper is divided as ink layer and paper layer. The mass transfer coefficient hm and partition coefficient KF,P in the interface between paper and food are considered in the model. The model equation is solved, and the migration expression is obtained by using the method of separation of variables. The fitting method is used between the model and the migration experimental data to obtain the diffusion coefficients and mass transfer coefficients for dibutyl phthalate (DBP) and acetyl tributyl citrate (ATBC). It is found that there exist linear relationships between ln( DP) and 1/ T, and also between ln( hm) and 1/ T for DBP and ATBC. The migrations of DBP in the paper sample 2402 at different temperatures and of ATBC in the paper sample 2401 at 50°C are predicted by using the model, and a good agreement is obtained between the model predictions and the migration experimental data.

Paper‐based composite packages, which have been widely used for beverage in modern daily life, are featured of nutrition preservation and convenience. However, it is also causing environmental problems in urban areas because of the low recycling rate. The introduction of extended producer responsibility (EPR) is helpful to improving the recycling rate of beverage paper‐based composite packaging by extending the producer's environmental‐protecting responsibility for the product from its production to its end‐of‐life treatment. To find out the optimal strategy of applying the EPR system for beverage paper‐based composite packaging, this paper is conducted based on the basic framework of the EPR system, combined with the specific requirements of the EPR System Implementation Plan promulgated by China and the Implementation Plan of the EPR System for Beverage Paper‐Based Composite Packaging. An evaluation index system for beverage paper‐based composite packaging manufacturers is constructed to perform the EPR system, including three management‐level indicators, 10 standard‐level indicators and 42 programme‐level indicators. A comprehensive evaluation method is introduced to help the producers to fulfill the extended producer responsibility. Results suggest that beverage paper‐based composite packaging producers should first fulfill the responsibility in information disclosure, ecological design and use of recycled materials.

Mango fruit is perishable and susceptible to anthracnose. Active‐coated paper is proposed as potential packaging for commercial application in wrapping mango fruit to control anthracnose and delay the ripening process of fruit. The surface of white standard bleached paper was coated using a vanillin‐chitosan coating solution containing varying amounts of zeolite or activated carbon at 0% (vanillin paper), 0.1%, 0.2%, and 0.4%, w/v of ethylene absorbers. The first objective was to study the effect of absorber types and their amounts on ethylene removal. After that, the coating formulation that provided the highest ethylene removal was selected to wrap commercial Nam Dok Mai mango fruit to study the quality changes. The efficacy of active‐coated paper on the severity index of anthracnose disease, change in physicochemical properties, and sensory acceptability during storage (13°C, 90% relative humidity (RH) for 30 days) were investigated. It was found that vanillin‐chitosan coated paper containing 0.2% (w/v) of zeolite (zeolite paper) exhibited the highest capacity of ethylene adsorption. Zeolite paper could delay the disease incidence of wrapped mango fruit and provided the lowest severity index of anthracnose disease throughout storage. Moreover, changes in physicochemical qualities (weight loss, firmness, titratable acidity, total soluble solid, and color) of mango fruits wrapped in zeolite paper was quite low, compared with those wrapped with vanillin and uncoated papers. In addition, mango wrapped by zeolite paper had the highest sensory acceptance score. The results suggest that zeolite paper can efficiently be applied as wrapping to extend the postharvest life of mango fruit. [ABSTRACT FROM AUTHOR]

This study demonstrates a method to quantitatively measure the oleophobicities of food packaging paper via using a tracer‐assisted headspace gas chromatography by adding a 40‐μL droplet of toluene‐doped oil onto a sample surface, wherein toluene behaves as volatile tracer. After 20 s, the sample was turned vertically to remove the oil and placed in a headspace vial. The amount of toluene in the residual oil adhered to the sample surface was quantified using headspace gas chromatography under full‐evaporation conditions. The results exhibit satisfactory precision (RSDs < 2.5%) and provide quantitative information on oleophobicity. The proposed method is simple, efficient and suitable for batch sample testing.

The high humidity produced by the ripening of fruit and vegetables during refrigerated storage and transport leads to a noticeable loss of strength of corrugated board packaging. Increasing use of recycled fibres in the manufacture of corrugated board further reduces box compression strength. Adding virgin fibres to the furnish composition of liner paper could solve this problem. Various proportions of unbleached virgin eucalyptus and pine fibres were added to a recycled furnish used to manufacture liner paper for corrugated board. Laboratory sheets of each fibre blend were characterised by tensile, bursting and compressive strength. The change in the strength properties and moisture content of the sheets during refrigerated storage at 6°C and high relative humidity (90% RH) was also studied. The results showed that paper strength improved with the proportion of virgin fibres added. Pine fibres yielded higher increments than eucalyptus fibres in tensile and burst indices, whereas both fibres improved compression strength at a similar rate. After 4 h of exposure at refrigerated storage, the paper strength properties decreased considerably, in particular compression strength, which showed a loss of about 70% compared to the reference value. The percentage of strength lost compared to the value in standard conditions was influenced only by exposure time at low temperature and high RH. However, an increase in the amount of pine fibres added enhanced the remaining tensile and burst indices. [ABSTRACT FROM AUTHOR]

With the growing emphasis on minimization of global plastic waste, flexible fibre‐based packaging has gained significant interest over the past few years. Heat‐sealing technology is commonly applied for vertical form‐fill‐seal machine to provide tight closure of packages for maintaining food quality and shelf life. Several different seal bar geometries and adequate heat‐seal parameters are required to improve the seal tightness of the packages. This study aims to compare the heat sealability of thermoplastic film (OPP/PE) and paper‐based materials in vertical form‐fill‐seal machine using various seal bar profiles. The investigation includes seal strength measurement, understanding the causes of leak formation, seal tightness and inspection of the seal using scanning electron microscopy. Results reveal that OPP/PE material has exceptional seal strength and leakproof ability compared with paper‐based materials. However, it has limited operating window because the material shrinks and coarsens at approximately 140°C. Sealing temperature and dwell time are found to be the major factors affecting the seal strength of paper‐based material. Results reveal the PE‐coated papers exhibit nearly twice the seal strength compared with the dispersion‐coated paper. It was difficult to achieve good hot‐tack values with dispersion‐coated paper. During testing, all the paper‐based materials experience delamination and fibre tear, and its severity increases with the increasing material grammage. As plateau temperature is reached, the fibre delamination remains relatively constant. The serrated geometry of seal bar design plays a significant role in providing a satisfactory airtight seal, particularly around the pouch's layer jump. However, flat seal bar designs are not recommended for gas tight applications for paper‐based materials. [ABSTRACT FROM AUTHOR]

A novel cost‐saving coat was applied on paper sheets to enhance their air, water vapor, and oil resistance to be used in the packaging purposes. This coat is based on new ingredients including core‐shell pigment CoO.ZnO/SiO2, which is composed of silica fume waste comprising 80% of the new pigment covered with the chemically and thermally stable binary oxide of CoO.ZnO with very low cobalt oxide content. This pigment was bind to the cellulosic fibers using sodium alginate, which is now broadly used due to its high oil resistance and enhanced grease proof properties. The addition of this novel coat to paper sheets changed drastically their mechanical and barrier properties rendering them with higher air, water vapor, and oil resistance. [ABSTRACT FROM AUTHOR]

Flexible packaging materials consisting of several layers of very dissimilar materials are currently considered for replacement by multilayer polyolefin films as well as functional flexible paper materials to improve recyclability. Such materials however lead to new challenges in processing on existing packaging machinery. This paper focuses on the sealing process of such materials, especially looking at pillow pouches and the challenges occurring at the junction between cross and fin seals where the total thickness jumps from two to four layers. It is shown that the application of conventional machinery and sealing tools does not lead to a gastight seal within the operational sealing window of such materials. The origin of the permanent failure is the lack of material fraction capable to flow as a viscous melt into the gap at the fin seal. The limited compressibility of the nonmelting materials and their bending stiffness tend to increase the gap. In case of paper, a flexible sealing jaw, equipped with an elastic insert, enables a focused application of pressure at the layer jump of a poorly compressible material. This results in clearly improved gas tightness of all selected materials in the range of the used test methods (leak size 10 μm). The leakage rate of papers was reduced from 3–4 mbar·l/s with rigid tools to 1 mbar·l/s with flexible tools. The leakage of 2 mbar·l/s with OPP/CPP material could be prevented and no leaks were detected. With OPP/PE, leak‐proof results were obtain within reduced temperature at 140°, which is near the level of acceptable seal quality with low shrinkage effect. [ABSTRACT FROM AUTHOR]

Heat sealing behavior of mono‐polyolefins and paper‐based materials is drastically different from conventional multilayer plastic laminates. This paper presents the effect of sealing conditions on Hot‐Tack and Cold‐Tack for an oriented polypropylene (OPP)‐based polyolefin laminate with either polyethylene (PE) or cast polypropylene (CPP) sealing layer and two different barrier paper materials carrying a thin acrylic copolymer sealing layer. The investigations include pressure, temperature, time, jaw pattern, and climate conditions (moisture). It is shown that the mono‐polyolefins reach comparable Hot‐Tack and Cold‐Tack ranges compared with the reference polyethylene terephthalate (PET)‐aluminum (Al)‐PE laminate. The CPP laminate exhibits a narrow sealing window near the range in which shrinkage is observed. While for the polyolefins temperature plays the main role, the sealing of paper materials turned out to be dependent on pressure, time, and moisture content in paper. Due to a rupture through the polymer thin coating, the Cold‐Tack is dominated by a delamination of paper and coating. Consequently, the Cold‐Tack is drastically lower than with PET‐Al‐PE laminate. Monopolypropylene films exhibit extremely narrow sealing window, which shall be taken into the design consideration of bag form‐fill‐seal (FFS) machines. Polymer coated paper can be potentially used at high‐speed FFS; however, special attention shall be paid to moisture content control and filling. [ABSTRACT FROM AUTHOR]

1‐Methylcyclopropene (1‐MCP) has been shown to be a suitable inhibitor of ethylene production in fruit and vegetables during preservation and distribution. In this study, a 1‐MCP controlled‐release system on coated paper was produced using shellac as the coating material. The effect of humidity and temperature on the release of 1‐MCP from the coated paper was investigated using a dynamic sorption system (DVS) with stepwise humidity changes (initial 20% relative humidity (RH) for 2 h, then increased to 40%, 50%, 60%, and 80% RH for 2 h, respectively). The release rate kinetic data were simulated using an Avrami equation with a mechanism release number n of 1.26. The results showed that the dynamic release of 1‐MCP from the coated paper was mainly affected by humidity, for which the release rate constant could be correlated with moisture concentration in humid air. The highest humidity condition (80% RH) resulted in the highest apparent activation energy of 46.8 kJ/mol. The effect of 1‐MCP coated paper on apple storage was evaluated by measuring the ethylene production rate, flesh firmness, and titratable acidity (TA) of apple. Ethylene production rates of apple were significantly affected with 1‐MCP coated paper. The values were 0.22 nL/g FW/h at 50 mg of 1‐MCP powder and 44.7 nL/g FW/h at 0 mg of 1‐MCP powder after 15 days at 4°C and 15 days at 20°C. The other properties of apple such as flesh firmness and TA also indicated that 1‐MCP coated paper could delay fruit softening during storage time. Based on these results, the release of 1‐MCP could be controlled by coating paper with shellac solution and promising to produce functional packaging for fruit. [ABSTRACT FROM AUTHOR]

An airflow‐induced separation method for stacked paper labels is proposed with a stream of compressed air used to jet vertically onto the side of the stacked labels and force constraints applied to the two ends of the labels. Its mechanism is revealed that the viscous force caused by airflow is the main driving force for the initial separation of labels and the vertical force is the main factor for the formation of successive separation channels. Theoretical and experimental analyses are implemented to ensure the effects of airflow velocity, label characteristics, label stress, and other factors on label separation and show that a stable separation gap can be generated with separation efficiency of more than 3600 sheets per minute and reliability of 99.99%. A complete airflow‐induced label separation device is designed, which can be integrated into the existing packaging machine, and the physical feasibility of the stack label separation method is verified by experiments.

Slip‐preventing materials are often used as tertiary packaging to improve cargo securement and simplify truck loading. There are many national and international standards on their safe usage based on the extra friction they can provide. However, it is challenging to quantify the coefficient of friction (CoF) of slip‐preventing materials. This paper presents CoFs of three slip‐preventing materials and one baseline condition measured on different surfaces and contact pressures. These measurements show interesting phenomena that affect the result variability. For instance, 60% of the pairs of surfaces tested were affected by the contact pressure. Hence, the load of the freight seems to affect performance of the slip‐preventing materials. This interaction happened in different ways such as changes in the friction mode (constant slip and stick slip at difference frequencies and magnitudes). The typical CoF values available in standards as well as standardized measurement methods do not consider very well these effects nor how to deal with high variability of CoF measurements. This can lead to either over or under CoF estimations. To overcome these limitations, this paper presents a statistical method to quantify slip‐preventing material CoFs based on variability and confidence intervals of the measurements.

As the food and pharmaceutical industries move toward more sustainable forms of packaging, paper is experiencing somewhat of a comeback as a packaging material. However, by its very nature paper is rich in volatiles—both with and without significant olfactory impact. Human sensory analysis has long been the benchmark for determining that a product is fit for consumer application. However, sensory analysis is limited in its application due to the high per‐sample cost. Selected ion flow tube mass spectrometry (SIFT‐MS) is an instrumental approach that has potential to rapidly screen paper samples for both sensory and chemical composition attributes in a single broad‐spectrum and sensitive analysis of volatiles. In this study, a combined approach utilizing SIFT‐MS sample analysis with multivariate statistical data processing is evaluated for its ability to distinguish between samples of different paper composition (in particular, virgin, recycled, or mixed fibres), mill of origin (manufacturing mill), sensory odour intensity rating, and sensory odour note. Paper samples from four mills were analysed using instrumental and sensory methods, together with one pulp sample. The key discriminating volatiles varied depending on the classification model but typically included hydrogen sulfide, ethanol, acetone, hexanal, dimethyl sulfide, and formaldehyde. The pulp sample generally exhibited significantly higher concentrations of volatiles—especially methanol and hydrogen sulfide. Because it was so different, it was eliminated from certain models—in particular, for determination of the mill of origin. Chemical analysis with multivariate statistical processing exhibited near‐perfect classification of the fibre type and the mill of origin. Evaluation of instrumental prediction of odour intensity rating and odour note used multivariate statistical analysis to correlate sensory and instrumental results. It was found that concentration data provided superior classification of odour intensity rating and odour note than did odour activity values (compound concentrations divided by their human odour detection thresholds [ODTs]). This result is tentatively attributed to significant uncertainties introduced by literature ODTs and the method's limit of quantitation being higher than the ODT for several compounds. When using SIFT‐MS concentration data—when coupled with multivariate statistical data processing—this preliminary study demonstrates potential for rapid, instrumental determination of the odour intensity rating and odour note traditionally determined using human sensory analysis.

An analytical survey of 20 paper and board (P&B) materials intended for food use was carried out with the aim to identify chemicals with a potential to migrate into foods. Representative materials covering a range of uses (primary and secondary packaging and article for take away foods) were obtained from distributors. A screening approach was applied by means of solvent extraction with subsequent analysis by gas chromatography/mass spectrometry. A large number of analytes were detected, and a chemometric approach was used to explore the data. Principal component analysis was used to identify and select some compounds as markers for sample classification. In the corrugated and printed packaging, it is worth emphasizing the presence of residual solvents, probably coming from printing inks, as well as hydrocarbons and aromatic compounds, mainly toluene and plasticizers linked also to the recycled pulp content such as diisobutyl phthalate or diisopropylnaphthalenes, whereas in the plastic-laminated samples, triacetin was identified as the prevailing compound. A literature search for safety data or legislative restrictions of the identified substances was performed. Additionally, the semi-quantification of the compounds in the packaging allowed a worst case estimation of food contamination by means of the infinite total migration model; occasionally, migration estimations overcame the specific migration limits. The chosen analytical methods coupled with a chemometric approach proved to be an effective way to describe the data; it may be concluded that only the simultaneous consideration of several chemicals with a multivariate approach allowed the investigated packaging materials to be distinguished.

A moisture-dependent and temperature-dependent constitutive model for paper materials was proposed and implemented into a finite element model of the paper hydroforming process. Experimental hydroforming was conducted at temperatures of 23°C and 110 °C and moisture contents of 6.9 and 10.6 (respectively corresponding to 50 and 80% relative humidity). The proposed model, which also included the effects of drying, captured the extent of forming of all experimental results within reasonable accuracy. For the moisture content and temperature conditions in this study, the phenomenon of drying was found to be the reason why the application of temperature had a much greater effect on the degree of forming than hydroforming at various moisture contents. A simulation-based parametric study was conducted in order to identify the importance of various process and material parameters. This parametric study confirmed many previous empirical findings and was capable of quantifying the extent to which these process and material parameters affect the three-dimensional formability of paper. The coefficient of friction was identified as one of the most important factors when determining the extent of forming. Copyright © 2016 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Trametes versicolor laccase papers were prepared, and their suitability was tested for anticounterfeiting and oxygen indicator concepts in packaging applications. Laccase was coated and printed onto paper with a flexographic ink base, a sulfo polyester resin, Hydro-Rez 1100D (HZ1100D). Laccase remains active on paper with flexographic ink HZ1100D after printing with flexographic press. Colour change of papers was observed when 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) solution was applied to the paper. A strong colour change to dark green was obtained on the papers prepared by coating or printing of laccase with HZ1100D onto EUCA paper. EUCA paper appeared to be well suited for laccase-based indicator applications because it remained rough even after ink deposition, allowing rapid absorption of ABTS solution. Finally, the indicators demonstrated to work as oxygen indicators in a package. Indicator colour was changed when oxygen was leaked to the package. As a conclusion, the laccase papers described here would be well suited for various indicator applications and could be produced using flexographic printing, allowing large scale manufacturing.
