Effects of Cigarette Paper and Tipping Paper on Moisture and Tar Contents in Cigarette Smoke

The influences of cigarette paper with different permeabilities and different grammages and the perforated tipping paper with different permeabilities on the moisture and tar contents in cigarette smoke were investigated. The results showed that:1) when the permeability of cigarette paper increased by 10 CU, the moisture and tar contents in smoke decreased by 0.122 mg/cig.(about 2.94%) and 0.3 mg/cig.(about 1.93%), respectively; 2) with the increase of grammage of cigarette paper, the moisture content increased while the tar content decreased; however, when the grammage of cigarette paper was over 28 g/m², the change of moisture and tar contents diminished; 3) when the permeability of perforated tipping paper increased by 100 CU, the moisture and tar contents decreased by 0.3 mg/cig. (about 12.14%) and 1.32 mg/cig. (about 9.7%), respectively. In view of keeping moisture content and reducing tar in cigarette smoke, it was preferred to use cigarette paper with permeability of <70 CU and grammage of >28 g/m² and tipping paper with low permeability.
