In order to study the factors affecting the design of low ignition propensity (LIP) cigarette, cigarette samples were made of the same tobacco compositions and wrapped with ordinary cigarette paper or banded cigarette paper, the band diffusivity, full length burn rate and deliveries of mainstream smoke were determined, the results showed that: while keeping other conditions unchanged, 1) the ratio of full length burn of LIP cigarette increased by more than 60%, the deliveries of tar, nicotine and CO decreased by 4.0%, 6.5% and 6.1%, respectively, when the band diffusivity increased by 0.22 cm/s; 2) the ratio of full length burn of LIP cigarette increased by about 20%, the deliveries of tar, nicotine and CO decreased by 9.3%, 7.9% and 12.7%, respectively, when the content of combustion improver increased by 0.8%; 3) at higher combustion improver content, the width/space of band obviously affected the ratio of full length burn but not the deliveries of mainstream smoke.
