Disclosed is a stabilized substrate composition for smoking articles, particularly cigarettes. In general, the stabilized substrate composition comprises an admixture of a binder and an aerosol forming material which plasticizes the binder, together with optional fillers and/or base materials. In the stabilized substrate compositions of the present invention the relative amounts of binder and aerosol former depend particularly on the situation in which the substrate composition is used. In general, the ratio of aerosol former to binder is between about 3:1 and about 40:1. When the stabilized composition is used on a base material such as tobacco cut filler, the ratio of aerosol former to binder should be at least about 15:1, and preferably is from about 25-35:1, with a maximum ratio of about 40:1. If the composition is formed into a cast sheet, the minimum ratio is about 3:1, the preferred ratio is about 8:1, and the maximum ratio is about 10:1. When the stabilized mixture is printed on a sheet or web substrate, the ratio of aerosol former to binder is generally about 6:1, the maximum ratio is about 10:1, and the minimum ratio is about 3:1.
A stabilized substrate composition, comprising an admixture of an aerosol forming substance, in an effective amount to provide a smokeable aerosol, and a binder which stabilizes the aerosol forming substance, wherein the ratio of the aerosol forming substance to the binder is in the range of from about 3:1 to about 40:1, and where the binder comprises an alginate binder.
The stabilized substrate composition of claim 14, wherein the moisture content of the substrate composition is from about 8 to 12%.
A stabilized substrate composition, comprising tobacco cut filler as a base material to which has been applied an admixture comprising a polyhydric alcohol, in an effective amount to provide a smokeable aerosol, and a binder plasticizable by said polyhydric alcohol, wherein the ratio of the polyhydric alcohol to binder is from about 15:1 to about 40:1.
A stabilized composition, comprising a reconstituted tobacco paper sheet as a base material to which has been applied an admixture comprising a polyhydric alcohol, in an effective amount to provide a smokeable aerosol, and a binder plasticizable by said polyhydric alcohol, wherein the ratio of the polyhydric alcohol to binder is from about 3:1 to about 15:1.
A stabilized substrate composition comprising a glass fiber mat as a base material to which has been applied an admixture comprising a polyhydric alcohol, in an effective amount to provide a smokeable aerosol, and a binder plasticizable by said polyhydric alcohol, wherein the ratio of the polyhydric alcohol to binder is from about 3:1 to about 15:1.
The stabilized composition of claim 25, wherein the ratio of polyhydric alcohol to binder is in about 10:1.
A stabilized substrate composition, comprising an admixture of a filler material, a polyhydric alcohol aerosol forming material, in an effective amount to provide a smokeable aerosol, and a binder, wherein the ratio of the polyhydric alcohol to the binder ranges from about 15:1 to about 40:1.
A substrate for smoking articles, comprising a base material in the form of a sheet, mat, or webs said base material having a film or coating thereon comprising a stabilized aerosol forming composition comprising an admixture of a polyhydric alcohol aerosol former, in an effective amount to provide a smokeable aerosol, and a binders wherein the weight ratio of the aerosol former to the binder ranges from about 15:3 to 97:3.
A substrate for smoking articles, comprising a tobacco sheet or web, which is coated with a film composition, in an effective amount to provide a smokeable aerosol, comprising a stabilized admixture of from about 20% to about 85% of a polyhydric alcohol aerosol forming material and from about 1% to about 25l % of a binder.
