Influence of low ignition propensity (LIP) cigarette paper on ignition strength and combustion coal temperature of cigarette
The ignition behaviour of 6 cigarette samples wrapped in papers of different ignition propensities (2 ordinary cigarette papers, 4 LIP cigarette papers) was studied. The influence of burning additive and band width/space on ignition behaviour of cigarette was studied on the basis of the mean surface temperature of combustion coal while smouldering and CO content in mainstream cigarette smoke. The results showed that 1) especially the content of burning additive in and the band width/space on the LIP cigarette paper play an important role in the ignition strength of cigarette; 2) the ignition strength of LIP cigarette correlates to the mean surface temperature of combustion coal. 3) the content of burning additive has an influence on the mean surface temperature of combustion coal and CO yield, while the influence of band width/space is not observed.
