Abstract (en)
The present invention relates to a method of producing a smoking article wrapper with reduced ignition propensity. Specifically the present invention relates to a method of producing a wrapper for a smoking article comprising the steps of: (a) providing a wrapper; (b) applying one or more additives to the surface of the wrapper to form regions of applied additive having reduced porosity and/or reduced oxygen diffusion sufficient to reduce the ignition propensity of a smoking article and regions having substantially reduced or zero additive such that the wrapper maintains its physical integrity during processing and has improved visual appearance by reduced wrinkling; and (c) machining the wrapper to form a wrapper which upon incorporation in to the smoking article forms rings of additive.
