Abstract
A tobacco-containing paper is provided using a reconstituted tobacco material as a component thereof. A reconstituted tobacco material, provided using papermaking techniques from a refined tobacco pulp, is refined into a pulp form and provided as a slurry in water. The slurry is combined with inorganic filler (e.g., calcium carbonate particles) and cellulosic pulp (e.g., wood pulp). The resulting slurry is then employed to provide a paper using papermaking techniques. The tobacco-containing paper has many desirable physical characteristics.
