Tobacco-Containing Wrapper Having A White Brilliant Appearance

Abstract

A wrapping material is disclosed that contains from about 10% to about 60% of a tobacco material. The tobacco material has a relatively large particle size. For instance, the tobacco material may have a particle size distribution such that greater than 80% of the tobacco particles and fibers have a greatest dimension of greater than about 0.025 inches. The tobacco material is combined with bleached pulp fibers and a filler and formed into a web using a papermaking process. The wrapping material has a distinct natural appearance and a less papery taste in relation to conventional cigarette papers. The wrapping material has a brighter, whiter look than conventional reconstituted tobacco wrappers and produces a smoother smoke with better ash appearance.
