Paper Combustibility : Cigarette Combustibility?

귈련지 연소성과 담배 연소성과의 관계는?

Up to the 60's cigarette paper commercial grades were simply described as ' non combustible ', ' combustible ' or ' extra-combustible '. It was assumed that combustibility of the paper itself was correlated with cigarette combustibility. Since then, the characteristics of cigarette paper, like natural porosity and burning additives, which influence truly cigarette combustibility, have been described by various authors and it became clear to cigarette designers that paper combustibility was not generally a significant factor governing cigarette combustibility. On the other hand, for Roll Your Own(RYO)wrapping papers, the ECPCI has proposed to the CORESTA RYO Task Force to use paper combustibility, and specially the LCT test, to classify papers between low and high smoke delivery, and a new Task Force on PAPER COMBUSTIBILITY was recently set up to develop a recommended method. The objective of this presentation Is to show results demonstrating that for paper used on cigarettes, there is NO GENERAL CORTRELATION between PAPER and CIGARETTE combustibility. We will also show results confirming that, for the specific group of RYO booklet papers containing no burning additives, there is a correlation between paper combustibility and FCSA's Combustibility/smoke delivery. This apparent discrepancy will be explained by reviewing the role played by the various characteristics of cigarette paper in governing cigarette combustibility.
