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.

Wrapper for a smoking article

A paper wrapper for a cigarette is prepared using fine particle size calcium carbonate as the mineral filler for the purpose of burn rate, puff count and tar delivery control.

Cigarette and wrapper with controlled puff count

The calcium carbonate filler level or the basis weight of a paper wrapper for a smoking article is varied to enable the designing of smoking articles with specific characteristics including a specific puff count, tar delivery and carbon monoxide delivery.

Smoking articles using novel paper wrapper

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.

Paper wrapper having improved ash characteristics

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.

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.
