This book discusses a major issue in the food contact materials industry: non-intentionally added substances (NIAS), and their impact on PET-bottled water. NIAS are chemical compounds that are present in food contact materials but have not been added for technical reasons during the production process, and consumers are usually unaware of their presence. NIAS can include decomposition or degradation products, impurities in the raw materials, unwanted by-products or contaminants from recycling processes, and they pose a challenge for packaging manufacturers.In Europe, the EU Regulations No. 1935/2004 and 10/2011 set out, respectively, the general principles of safety and inertness for all packaging materials, and rules on the composition of plastic food-contact materials. Among the plastics commonly used for bottled water and other non-alcoholic refreshment beverages, polyethylene terephthalate (PET) is the most favoured thanks to its chemical and physicalstability, its transparency, low weight and good recyclability. Further, very few additives are used for its manufacture. Nonetheless, due to the complex formulations of polymers, processes and storage, NIAS can also be found in PET-bottled water, with potential cancerogenic or toxic effects.This book provides an overview of the European regulation of NIAS in plastic packaging materials, offering insights into their chemical composition in PET-bottled water. Lastly, it provides a useful discussion on NIAS and their toxicity.

Poly(Ethylene Terephthalate) (PET) is an industrially important material which is not treated specifically in any other book. Poly(Ethylene Terephthalate) Based Blends, Composites and Nanocomposites fills this gap and systematically guides the reader through all aspects of PET and its blends, composites and nanocomposites. It covers theoretical fundamentals, nanocomposites preparation, modification techniques, structure-property relationships, characterisation of the different blends and composites, and material choice for specific applications. Consisting of contributions from experts in the field this book is a useful reference for the researchers and engineers working on the development and characterization of PET materials as well as on implementing them in real-world products. It can also be used as a standard reference for deeper insight in the mechanical, thermal, thermo-mechanical and visco-elastic aspects in product design decisions. - Provides a systematic overview on all types of poly(ethylene) terephthalate (PET) based blends, composites and nanocomposites - Informs about characterization, structure-property relationships and types of modifications - Links material properties to specific applications, enabling engineers to make the best material choice to increase product performance and cost efficiency, in industries ranging from aerospace to energy
