Abstract
A method for producing a diffusion-optimized tipping paper for tobacco products, especially filter cigarettes, by plasma perforation of the web of tipping paper for the purpose of maximum carbon monoxide reduction, wherein the diffusivity and the permeability P of the perforated tipping paper are measured in-line and diffusivity is maximized by controlling the perforation parameters, the definable target permeability Psoll being maintained at all times.
