Water-dispersible sheet for cigarettes and cigarette using the same |
摘要 |
A water-dispersible sheet for cigarettes and a cigarette using the sheet are described. The sheet comprises a water-resolvable base paper and a water-dispersible coating layer containing water-soluble polymer formed on the surface of the base paper, whereby the sheet is adjusted to have an air-permeability of not more than 200 coresta measured with a paper permeability meter, or to have an air-resistance within the range of 0 to 50000 second/100 ml measured with an Oken type air-resistance tester. The water-resolvable base paper is made from fibrous raw materials containing not less than 20% by weight of water-dispersible fibers having fiber dimensions of a l/D value of 0.45 or lower and a L/D value of 60 or lower and a water-retention value of 95% or lower. The sheet is suitable for use as filter joining paper or filter plug wrap for cigarettes.
