Abstract
A novel reconstituted tobacco sheet material is provided which is useful in providing a novel smoking product which has a smoking quality closely approximating that of cigarettes having conventional paper wrappers. The reconstituted tobacco sheet is prepared by a paper-making process in which the water-soluble material extracted in the paper-making process is not added back to the sheet, or if added back, to an extent of no more than 20 wt % of the reconstituted tobacco sheet. In the novel smoking product, a tobacco filler rod is enclosed within an outer wrapper, which usually comprises an inner binder layer and an outer wrapper layer, one or both formed of reconstituted tobacco sheet material. When the tobacco filler rod is double-wrapped, the novel smoking product also exhibits a significant reduction in sidestream smoking production in comparison to a conventionally-wrapped cigarette. The reconstituted tobacco sheet material has a porosity of at least about 50 Coresta units and contains about 10 to about 20 wt % of conventional chalk-type fillers.
