Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a paper wrapper containing cellulosic fibers and filler particles. The paper wrappers are treated with a film-forming composition in order to reduce the ignition proclivity characteristics of the smoking articles. In one embodiment, the film-forming composition contains an alginate combined with a starch. In an alternative embodiment, the film-forming composition contains a film-forming material combined with filler particles. The filler particles may comprise kaolin clay, magnesium oxide, mica, alum, or mixtures thereof.

Smoking articles having reduced ignition proclivity characteristics

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.

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 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.

Smoking articles with reduced ignition proclivity characteristics

Wrappers for smoking articles are disclosed having reduced ignition proclivity characteristics. The wrappers include discrete areas treated with a reduced ignition composition. In accordance with the present disclosure, the amount of burn promoting agents is controlled over the surface of the wrapper in order to, in one embodiment, increase the permeability of the treated areas.
