Abstract
A method for controlling the permeability of a wrapping paper for smoking articles is disclosed. Specifically, the permeability of the paper is varied by incorporating into the paper a filler material having a particular particle size. In one embodiment, for instance, a filler having a size larger than conventional sized fillers is incorporated into a wrapping paper for significantly increasing the permeability of the wrapping paper. For instance, wrapping papers can be constructed in accordance with the present invention having a permeability of greater than 80 CORESTA units without having to perforate the papers.
