Carbon filled wrapper for smoking article

Abstract

Abstract A carbon filled wrapper for smoking articles such as cigarettes, cigars and the like which significantly reduces the total particulate matter yield and organic vapor phase constituents in the mainstream smoke therefrom while simultaneously reducing the visible sidestream smoke. The carbon filled wrapper is preferably used as an inner wrapper for the tobacco column in combination with an outer wrapping of conventional cigarette paper or cigar wrap. The carbon content of the wrapper may vary over a wide range depending upon the effect desired. Various types of carbon, either activated or unactivated, may be used. Increased effects may be obtained if calcium carbonate is incorporated in the carbon filled sheet and the effects are further enhanced if the paper is treated with an oxidation catalyst such as the alkali metal hydroxides, bicarbonates and carbonates. The paper is also particularly suited as a means for introducing various flavorants to the cigarette since the carbon holds the flavor until released by the heat of the burning zone.
