Patent ID: 8863757

Claim:
A process for producing a paper wrapper having reduced ignition proclivity characteristics when incorporated into a smoking article comprising: applying a film-forming composition to a paper wrapper at particular locations, the paper wrapper comprising a paper web containing a filler, the paper wrapper having a basis weight of from about 18 gsm to about 60 gsm, said film-forming composition forming treated discrete areas on said wrapper, the treated areas being separated by untreated areas, the treated discrete areas having a BMI of less than about 5 cm −1 , the film-forming composition comprising a film-forming material contained in the composition in an amount sufficient for the composition to have a solids content of at least 6% by weight, the film-forming material having a molecular weight such that the film-forming material has a viscosity of less than about 500 cP when present in a 3% by weight aqueous solution at 25° C., the treated areas having a permeability up to about 40 Coresta, the treated areas reducing ignition proclivity of a cigarette incorporating the wrapper, the untreated areas of the paper wrapper having a permeability of about 55 Coresta to about 110 Coresta.
