Abstract:The effects of relative humidity on physical properties of the papers and filter using for cigarette production were studied by changing the environment relative humidity at the constant temperature conditions, the physical properties of the papers and filter at the corresponding relative humidity were measured and regression analysis was conducted. The results showed that: ① there is a linear correlation between paper's MD tensile strength, MD elongation, grammage and relative humidity. AP air permeability of cigarette paper, the tensile energy absorption index of tipping paper and plug wrap paper also have a linear correlation with relative humidity. ② The weight, circumference, hardness, and length of filter have a linear correlation with relative humidity. |
