Abstract: Wrapping materials are disclosed that are particularly well suited for producing roll-your-own smoking articles. In one aspect, the wrapping materials can be made from extracted Cannabis materials optionally combined with web building fibers. The extracted Cannabis materials are comminuted to a median particle size of generally less than about 120 microns, such as less than about 80 microns. At least one gum is incorporated into the wrapping material for producing a wrapping material with enhanced strength, very smooth surfaces, and excellent self-adhering properties.

Abstract: A wrapping material is disclosed that contains from about 10% to about 60% of a tobacco material. The tobacco material has a relatively large particle size. For instance, the tobacco material may have a particle size distribution such that greater than 80% of the tobacco particles and fibers have a greatest dimension of greater than about 0.025 inches. The tobacco material is combined with bleached pulp fibers and a filler and formed into a web using a papermaking process. The wrapping material has a distinct natural appearance and a less papery taste in relation to conventional cigarette papers. The wrapping material has a brighter, whiter look than conventional reconstituted tobacco wrappers and produces a smoother smoke with better ash appearance.

Abstract: A process of making a coated paper comprises the following steps: 1) providing a paper layer composed of a blend of pulp fibers and particulate material containing polyvalent metal cations, 2) applying a acidified alginate solution of a material selected from salts and derivatives of alginic acid to cover at least a portion of the paper, 3) reacting the salts and/or derivatives of alginic acid with polyvalent metal cations in the paper to form a polymer coating, and 4) drying the paper and polymer coating. The permeability of the coated paper is generally at least about 75 percent less than the permeability of an identical uncoated portion of the paper. The solution of alginate material may be partially cross-linked. The alginate solution may be deposited utilizing gravure printing techniques. Also disclosed is a coated paper and a wrapper for a smoking article.

Abstract: A heatseal porous plugwrap made with a naturally porous combiner wrap and spray-applied hot melt adhesive. The natural porosity of the combiner wrap paper and the superficial location of sprayed adhesive greatly inhibit the penetration of adhesive to the outer surface of the paper, thus minimizing the possibility that the adhesive will interfere with the tipping process. The use of a sprayer to apply the adhesive allows for only the required amount of adhesive to be utilized and thus eliminates waste.
