The effects of four factors (individual weight, combustion improver content in cigarette paper, moisture content in cut tobacco and sliver content in cut tobacco) on the burning cone fallout of super slim cigarettes were investigated by an in-house developed instrument. The results showed that the burning cone fallout ratio (BCFR) of super slim cigarettes decreased sharply with the increase of the individual weight of the cigarette, reduced obviously with a slight increase of moisture content in cut tobacco, lowered with the decrease of combustion improver content in the cigarette paper, and reduced slightly with the decrease of sliver content in cut tobacco. The data of a single factor analysis were normalized and the results suggested that a good linear relationship exists between BCFR and individual cigarette weight, the combustion improver content and the sliver content, while there was an inferior linear relationship between BCFR and the moisture content. Based on the single factor analysis, the influence of multiple factors on the BCFR of super slim cigarettes was simultaneously investigated by partial least squares (PLS) regression analysis using Minitab 17 statistics software. The independent variables and dependent variable presented significant correlations (p < 0.05). BCFR was positively correlated with combustion improver content and sliver content and negatively correlated with the other two factors. Individual cigarette weight was the most significant influencing factor for BCFR, followed by the combustion improver content, the moisture content and the sliver content, which agreed with the results of single factor analysis. On the basis of these results, a specific cigarette was manufactured and the BCFR decreased from 58 % to 32 % by increasing its individual weight properly.
