Abstract:
1. A smoking article having reduced ignition proclivity characteristics produced by a process comprising the steps of: providing an untreated paper wrapper; treating discrete areas of the paper wrapper by directly applying a film-forming composition to the discrete areas of the paper wrapper, the film-forming composition comprising a film-forming material and a first burn promoting agent, the film-forming composition being free of a burn retardant; applying a second burn promoting agent only to untreated areas of the paper wrapper, the untreated areas being free of the film-forming composition; wherein the treated areas containing the film-forming composition are separated by the untreated areas containing the second burn promoting agent, the treated areas having a permeability within a range sufficient to reduce ignition proclivity, the film-forming material comprising a material selected from the group consisting of an alginate, a guar gum, a pectin, a polyvinyl alcohol, a cellulose derivative, a starch, a starch derivative, and mixtures thereof; and wrapping the paper wrapper around a column comprising a smokable tobacco.
