Zusammenfassung:	A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition is applied as multiple layers to the paper wrapper. After each application step, the wrapper is dried. Applying the film-forming composition to the paper wrapper in multiple layers minimizes distortion and other adverse affects that may occur to the wrapper.
