Problems solved by technology

Since the surface of many cigarette films needs to be printed and aluminized, the printing is more difficult, and the problem of poor ink adhesion is prone to occur. In addition, after laser aluminizing, the adhesion between the aluminized layer and the film is poor, and it is easy to dealuminate. Affect the quality of cigarette film

Abstract

The invention relates to a printed cigarette film, and relates to an antistatic super-strong printed cigarette film which is prepared by extruding a functional layer, a core layer and a secondary functional layer, and the core layer is located between the functional layer and the secondary functional layer; the mass ratio of the functional layer to the core layer to the secondary functional layeris 3: 15: 4; the functional layer is prepared from the following raw materials in percentage by mass: 96 to 98 percent of ternary random co-polypropylene, 0.5 to 2 percent of antioxidant and 0.5 to 2percent of graphene; the core layer is prepared from the following raw materials in percentage by mass: 84 to 89 percent of homo-polypropylene, 8.5 to 13.5 percent of petroleum resin, 1 to 2 percent of internal lubricant, 0.5 to 2 percent of antioxidant and 1 to 3 percent of migration slipping agent; the secondary functional layer is prepared from the following raw materials in percentage by mass:0.5 to 1 percent of graphene, 0.5 to 1 percent of antioxidant, 41 to 57 percent of maleic anhydride grafted polypropylene and 40 to 57 percent of homo-polypropylene. The secondary functional layer further comprises nano-silver loaded graphene, a graphene loaded silicon dioxide composite material and carboxyl-containing hyperbranched polyester acrylate. The printed cigarette film has the advantages of being good in surface tension, good in printing fastness and good in anti-static effect stability.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a printed cigarette film, which is used for packaging cigarettes. Background technique [0002] Due to the poor polarity of BOPP film, even after corona treatment to increase the surface polarity, its surface tension is also low, and the general surface tension can only reach 30 dynes. The surface tension is only 28 dynes in a long time. Since the surface of many cigarette films needs to be printed and aluminized, the printing is more difficult, and the problem of poor ink adhesion is prone to occur. In addition, after laser aluminizing, the adhesion between the aluminized layer and the film is poor, and it is easy to dealuminate. Affect the quality of cigarette film. Contents of the invention [0003] The object of the present invention is to provide an antistatic super strong printed cigarette film, which has the characteristics of good surface tensi...
