Calendered ultraporous cigarette plug wrap, method of producing same and cigarettes made from the wrap

摘要

An improved tobacco filter or plug wrap is made by calendering ultraporous paper. The calendering process reduces surface irregularities, reduces the thickness of the paper, and reduces the porosity. In general, during the calendering step, the ultraporous paper should be reduced in thickness from about 0.1 mils. to about 2.5 mils.
