  • Embossed cigarette wrapper with improved holding force
    Patent number: 6019106
    Abstract: A cigarette has a shredded tobacco filler and a paper for wrapping the filler. Many frusto-pyramidal portions biting into the filler are formed so as to be distributed on an inner surface of the paper except on both of the side edge portions of the inner surface. The inner surface, so formed, provides a high coefficient of friction with respect to the shredded tobacco filler. This cigarette contributes to preventing the dropping of shredded tobacco from the cut end of the cigarette.
