<p>A wrapper is provided for smoking articles such as cigarettes, cigars and the like having incorporated therein at least 1% by weight of certain ceramic fibers in the paper furnish in combination magnesium oxide and/or magnesium hydroxide fillers, whereby the combination acts to significantly reduce visible sidestream smoke emanating from the smoking article during static burning, and improves ashing. Wrappers made according to this invention may be made by incorporating the magnesium hydroxide, magnesium oxide and the other fillers in the wrapper pulp furnish containing the ceramic fibers or either or both of the fillers may be applied to the improved wrapper as a coating for the papers. In the case of cigarette papers, the ceramic fibers may be added to an ordinary paper furnish such as pulped wood or flax fibers. The furnish of fiber pulp and ceramic fibers and fillers are used to make a paper sheet on conventional papermaking machines.</p> |
