Abstract: Cigarettes which yield low levels of visible sidestream smoke upon use employ a paper wrapping material having about 8 weight percent magnesium hydroxide, about 30 weight percent calcium carbonate and about 62 weight percent flax. The wrapping material has an inherent permeability of about 10 CORESTA units. The wrapping material contains an amount of water soluble alkali metal salt (e.g., potassium chloride and potassium malate) sufficient to provide at least about 35 mg water soluble alkali metal ions per gram of dry base web. The alkali metal salt normally is such that the wrapping material includes a significantly greater level of potassium ions than sodium ions. The wrapping material includes at least one organic acid.

Abstract: Processed smokable materials are provided by forming a slurry of combustible material (e.g., a carbonaceous material) in an aqueous liquid. The slurry then is contacted with a foaming agent which includes a mixture of a surfactant and a polymeric film-forming agent. The slurry is agitated to provide a slurry of decreased density. The slurry so provided then is formed into the desired shape and dried. The processed smokable material which results is useful as cut filler for cigarette manufacture.
