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

This invention relates to the control of the burn rate of a cigarette. The burn rate is controlled by the use of a paper wrapper to which regions of cellulosic material is applied and bonded. The cellulosic material is applied during a manufacturing step for the base paper wrapper, either off or on-line of the paper wrapper-forming machine.

Smoking article wrapper for controlling burn rate and method for making

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 single sheet of paper having multiple layers.
