Application of Mathematical Model for Ventilation Rate of Tipping Paper in Blended Cigarette Design

In order to obtain blended cigarette products with different tar deliveries, the relationship among the ventilation rates of cigarette, tipping paper and cigarette paper was investigated with single-line or two-line online laser perforation, and a mathematical model between the ventilation rate of tipping paper and tar delivery was established.The results showed that: 1) for cigarette of low ventilation rate, the ventilation rate of cigarette paper played a major role;while for cigarette of high ventilation rate, the ventilation rate of tipping paper played a major role;2) for blended cigarette products of low tar delivery, especially those with the tipping paper of about 45% ventilation rate, two-line online laser perforation should be adopted;for blended cigarette products of relatively higher tar delivery with low ventilation tipping paper, single-line online laser perforation was generally adopted;3) the parameters of online laser perforation could be adjusted according to the ventilation rate of tipping paper calculated with the mathematical model to meet the requirements of product design.
