ABSTRACT:
The present invention is directed to a method for controlling and adjusting the permeability of a cigarette wrapping paper. Permeability is controlled in the paper by adding different sized filler particles in different proportionate amounts. Permeability of the paper is altered without having to change the total amount of filler in the paper. By selectively controlling the permeability of the paper, various characteristics and properties of a cigarette made with the paper can be likewise modified as desired. In one embodiment of the present invention, the permeability of a cigarette wrapper can be automatically maintained or adjusted as the paper is being made.
