Abstract
A wrapper for a smoking article which, when wrapped about a tobacco column, provides improved sidestream smoke reduction, improved ash formation, and acceptable mainstream smoke taste and sidestream smoke odor subjectives. These objectives are attained by forming a single cellulosic sheet containing a filler comprising basic magnesium carbonate and, where desired, a co-filler of calcium carbonate. In addition, the sheet may be treated with a burning chemical such as alkali metal salts of organic carboxylic acids, and compatible acids.
