ABSTRACT:
A wrapper for a smoking article which, when wrapped about a tobacco column, provides improved sidestream smoke reduction, improved ash formation, and improved mainstream smoke taste and sidestream smoke odor subjectives. These objectives are attained by forming a single cellulosic sheet containing a filler combination of magnesium hydroxide activated carbon, and calcium carbonate. In addition, the sheet may be treated with a burning chemical such as potassium citrate, an organic acid such as citric acid, and a sugar such as sucrose. Considerable latitude exists in regard to sheet basis weight, filler levels, sheet porosity, burn rate and size press solution treatment in order to optimize product requirements.
