The paper wrapper includes a coating or a film of polymeric material and an organic filler material. A preferred polymeric material is nitrocellulose, and a preferred inorganic filler material of the coating is particulate magnesium hydroxide. The coating weighs about 0.05 to about 0.5 pound per 3,000 square feet of wrapping material.
