Description

Technical Field

[0001] The invention relates to the technical field of frame paper, in particular to a high-precision frame paper for cigarettes. Background Art

[0002] Cigarette frame paper is an indispensable material for tobacco packaging hard box products. It is mainly composed of white cardboard, aluminum foil layer or aluminized layer, glue, ink, etc. It plays a role in supporting the hard box packaging and protecting the cigarettes from being squeezed. In recent years, the appearance performance of cigarette frame paper has been increasingly valued by the market. The traditional processing technology of cigarette frame paper mainly includes direct printing on white cardboard, aluminum transfer, aluminum foil composite and other processes. Among them, white card printing frame paper has the advantages of simple process, strong plasticity of appearance, and excellent environmental protection performance without metal products, but it also has the defect of poor surface flatness. Even most white card printing frame papers have a layer of varnish applied on the outside of the ink layer to improve the flatness and friction resistance, but the effect is not ideal. The use of high-gloss glass cardboard as the base paper printing ink has the disadvantages of poor ink adhesion, easy fading and high base paper cost. The most important thing is that there is usually no pattern on the frame paper. Chinese patent CN202466317U discloses a cigarette frame paper, and the frame paper of the scheme is provided with a pattern area coated with a printing adaptability coating, and the pattern area is located in the recessed or raised part of the cardboard. The above scheme can only be used to print patterns in the pattern area, and the utilization of the frame paper is relatively small. However, if the method of first printing and then positioning die-cutting is adopted, it is easy to cause positioning die-cutting misalignment, resulting in the scrapping of the entire roll of printed materials.
