SMOKING ARTICLES WITH REDUCED IGNITION PROCLIVITY CHARACTERISTICS

摘要

A process for reducing the permeability of a paper wrapper (14) used in the construction of a smoking article (10) is disclosed. The paper wrapper (14) is treated with a film-forming composition that forms treated discrete areas (1 8) on the wrapper (14). The treated discrete areas (18) have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article (10) made with the wrapper (14). In accordan ce with the present invention, the film-forming composition contains a film- forming material. The film-forming material has a relatively low viscosity. In this manner, the film-forming composition can have a relatively high solids content and still be applied to the wrapper using conventional techniques, such as by using a gravure printer.
