Smoking article wrapper and method of making same

Abstract From the Canadian patent

A cigarette paper which when fabricated into a cigarette with a suitable tobacco column produces up to 80% less particulate sidestream smoke than do cigarettes fabricated with conventional cigarette paper wrappers. This reduction of sidestream smoke is accomplished by incorporation of a mixture of freshly precipitated and particulate magnesium hydroxides in the cigarette paper sheet as paper fillers. The high percentage reductions in sidestream particulate smoke are obtained when the median particle size of the particulate magnesium hydroxide filler is relatively large, e.g. 15 micrometers.
