Effects of perforation on filter ventilation rate and sensory quality of slim cigarrete.

In order to choose an appropriate perforation for improving the quality of slim cigarettes, effects of online laser, off-line laser, plasma and static electricity perforations on filter ventilation efficiency, filter ventilation rate stability and sensory quantity for slim cigarretes were investigated. The results showed that all of the four perforations could meet the design needs of filter ventilation rate. Higher filter ventilation rate could achieved of slim cigarettes perforated by plasma and static electricity when air permeability of tipping paper was fixed. Filter ventilation rate stability of slim cigarettes perforated by plasma and online laser was better comparatively. It was more beneficial for improvement of sensory quantity of slim cigarettes perforated by plasma and online laser. Sensory quantity of slim cigarettes perforated by these two ways was corresponded when the filter ventilation rate was lower, and that perforated by online laser was superior to perforated by plasma when the filter ventilation rate was higher. In conclusion, plasma and on-line laser perforations were better than static electricity and off-line laser perforations as a whole, and were the preferred punching methods in the prduction of slim cigarette.
