Novel materials for making low ignition propensity products are disclosed. Specifically, a treated cigarette paper for making low ignition propensity cigarettes are disclosed. The cigarette base paper containing a thermoplastic polymer aqueous suspension coated regions on a surface of the base paper so as to obtain coresta porosities of less than 15 is provided. This cigarette paper is further treated with a conditioning medium which is either water alone or water with a burning chemical such as an alkali metal containing organic salt either on the same surface bearing the thermoplastic polymer or on the opposite surface. The self-extinction characteristics of the cigarettes with the treated paper are improved. A method for making a cigarette paper for low ignition propensity cigarettes comprising a plurality of regions of a thermoplastic polymer aqueous suspension printed on to a surface of a base paper is also provided.
A cigarette paper for making low ignition propensity cigarettes comprising a base paper with a plurality of regions of thermoplastic polymer aqueous suspension printed on a surface of the paper wherein the plurality of regions of the base paper have Coresta porosities of 0 to 14.9,
A cigarette paper for making low ignition propensity cigarettes comprising a base paper with a plurality of regions of thermoplastic polymer aqueous suspension printed on a surface of the paper wherein the plurality of regions of the base paper have Coresta porosities of 0 to 14.9,
A cigarette paper for making low ignition propensity cigarettes comprising a base paper with a plurality of regions of thermoplastic polymer aqueous suspension printed on a surface of the paper, where in said aqueous suspension does not have fibrous cellulose, but has ethyl cellulose at a concentration of at least about 10% w/w and one other thermoplastic polymer and wherein the plurality of regions of the base paper have Coresta porosities from about 1.5 to about 10.
A cigarette paper for making low ignition propensity cigarettes comprising a base paper with a plurality of regions of thermoplastic polymer aqueous suspension printed on a surface of the paper, where in said aqueous suspension does not have fibrous cellulose, but has cellulose acetate phthalate at a concentration of at least about 10% w/w and one other thermoplastic polymer and wherein the plurality of regions of the base paper have Coresta porosities from about 1.5 to about 10.
