In order to achieve the above purpose, the technical scheme of the utility model is that an anti-counterfeiting aluminum foil composite paper for cigarette inner packaging is compounded with aluminum foil on one side of the base paper, and is characterized in that a watermark structure area with increased density is arranged on the base paper. The base paper mentioned here refers to all the paper suitable for adding watermark. Aluminum foil refers to aluminum foil commonly used in cigarette wrapping paper, and other metal foils can also be used. Watermark has been invented for more than 800 years. During this period, both papermaking technology and watermark suppression technology have made great progress, so the existing technology can completely produce a higher density watermark on paper. This watermark can be clearly seen or felt when observed under ordinary or reflected light, or when touched by hand. People think that watermark paper can only be observed by light, which is just the habit of production technology and traditional prejudice. The invention breaks this prejudice and combines watermark paper with aluminum foil. When people are used to seeing things in daily life (that is, reflecting observation) or touching them with their hands, it also produces anti-counterfeiting effect. The optimization scheme of this application is that the base paper with watermark structure area is ≤300g/m2.
The utility model overcomes the traditional concept that it is meaningless to set a watermark on the metal foil composite paper, and the provided anti-counterfeiting aluminum foil composite paper for cigarette inner packaging can be used for the inner packaging of various cigarettes, and is the same as the traditional aluminum foil composite paper in moisture resistance, odor resistance, compression resistance and deformation resistance. At the same time, the above watermark can effectively prevent counterfeiting. Because most small paper mills can't produce watermark paper; The manufacturing scale of watermark paper is high, so it is impossible to produce in small batches; At the same time, the state has very strict administrative control and management means for the production of watermark paper. Therefore, after adding watermark to the aluminum foil composite paper for cigarette inner packaging, it sets an insurmountable obstacle for counterfeiting, which can largely eliminate the production and sales of counterfeit and shoddy cigarettes.
Example 2 is basically the same as Example 2, but the base paper is 32g/m2 tissue paper.
Claim 1. An anti-counterfeiting aluminum foil composite paper for cigarette inner packaging is characterized in that aluminum foil is compounded on one side or both sides of a base paper, and a watermark structure area is arranged on the base paper.
2. The anti-counterfeiting aluminum foil composite paper for cigarette inner packaging according to claim 1, characterized in that the base paper with watermarked structural area is ≤300g/m2.
Patent abstract Anti-counterfeiting aluminum foil composite paper for cigarette inner packaging is composed of aluminum foil on one side of the base paper, which is characterized in that the base paper is provided with a watermark structure area with increased density. The utility model overcomes the traditional concept that it is meaningless to set a watermark on the metal foil composite paper, and the provided anti-counterfeiting aluminum foil composite paper for cigarette inner packaging can be used for the inner packaging of various cigarettes, and is the same as the traditional aluminum foil composite paper in moisture resistance, odor resistance, compression resistance and deformation resistance. At the same time, the above watermark can effectively prevent counterfeiting. Because most small paper mills can't produce watermark paper; Watermark paper has a high scale starting point, so it is impossible to produce in small batches;
