  • Wrapper for a smoking article
    Patent number: 5450862
    Abstract: The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a paper wrapper having an additive, such as an organic acid, an acidic or neutral salt or an organic acid in combination with an acidic salt or neutral salt added thereto.

  • Paper wrapper having improved ash characteristics
    Patent number: 5161551
    Abstract: The ash characteristics of a cigarette paper wrapper are improved by using fine particle size calcium carbonate filler. In addition, increased calcium carbonate filler loading level, increased basis weight, and various combinations of these variables are used to achieve improved ash characteristics.

  • Wrapper for a smoking article
    Patent number: 5152304
    Abstract: The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a paper wrapper having a burn modifier, such as an acidic salt, added thereto. Preferably the paper wrapper has a high basis weight and low porosity.

  • Smoking article exhibiting reduced sidestream smoke, and wrapper paper therefor
    Patent number: 4998543
    Abstract: The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a double layer of paper. Each layer includes calcium carbonate (i.e., about 30-40% by weight in the outer paper and about 2-15% by weight in the inner paper, the calcium carbonate in the outer paper having a surface area of about 20-80 square meters per gram by the BET method) and a burn control chemical. The outer layer also preferably includes monoammonium phosphate and sodium carboxy methyl cellulose. The calcium carbonate employed has a relatively high surface area per unit weight. The porosity of the outer layer is about 50-100 cubic centimeters per minute by the Coresta method, and may be adjusted by electrostatic perforation.
