Abstract

The invention discloses a black cigarette paper and a preparation method thereof. The cigarette paper comprises the following raw materials in parts by weight: 1-10 parts of food-grade carbon melanin,20-30 parts of a calcium carbonate filler, 5-30 parts of softwood pulp, 60-90 parts of hardwood pulp, 0.05-0.1 part of potassium oleate, 0.1-0.2 part of polyvinyl alcohol and 1-5 parts of other cigarette paper auxiliaries. The method is simple to operate and low in cost, the obtained black cigarette paper has the advantages of uniform and stable color, excellent color fastness, and safety. The appearance quality of cigarettes is effectively improved.

Description

technical field [0001] The invention relates to a cigarette paper, in particular to a black cigarette paper and a preparation method thereof, belonging to the field of cigarette tobacco materials. Background technique [0002] Cigarette paper, also called coil paper, is mainly used to wrap cigarette tobacco rods. Cigarette paper, as an important part of the "three papers and one stick" of cigarette accessories, not only carries the key image and connotation of the product, but also directly participates in the burning of cigarettes and has a special and direct impact on smoke. [0003] On the one hand, the burned components of cigarette paper itself are an important part of cigarette smoke, and are smoked together with mainstream smoke, so cigarette paper has an important impact on the smoking sensation of cigarette burning; on the other hand, the intrinsic quality of cigarette paper is also important. It will affect the combustion status of the cigarette, and has an import...
