ABSTRACT:
A smoking article wrapper having improved ignition proclivity characteristics includes discrete areas of an outer circumferential surface of the wrapper treated with a non-aqueous solution of a solvent soluble cellulosic polymer dissolved in a non-aqueous solvent. The solution also includes a particulate inorganic non-reactive filler suspended in solution by weight percentage of solution. The solution is applied in discrete areas as bands or patterns causing reduced permeability of the treated areas within a permeability range adequate to reduce ignition proclivity. A method is also provided for producing a smoking article wrapper having improved ignition proclivity characteristics as described.
