Problems solved by technology
[0008] 2. The anti-blocking agent particles migrating from the core layer to the surface layer of the film are dispersed widely, have no regular shape, and have high hardness
In addition, the dust particles attached to the surface during transportation and display are relatively hard
After these hard particles rub against the surface of the soft film, scratches and scratches will occur on the film, which will affect the appearance of the film.

Abstract
The invention utilizes a coating and printing method to respectively print a polyacrylic ester layer and a UV (Ultraviolet) curing coating on different positions of a cigarette packaging thin film aiming at the disadvantages of a three-layer structure of an existing cigarette film that the crystallization degree of a random PP (Propene Polymer) heat sealing layer is low, the hardness is small and the existing cigarette film is easy to wear. A heat sealing layer of an existing three-layer co-extruded cigarette film is copolymerized PP and is obtained by a method comprising the steps of extruding by a screw rod, casting a piece, stretching and carrying out heat setting; the method disclosed by the invention adopts a polyacrylic ester solution to coat on a BOPP (Biaxially-oriented Polypropylene) heat shrinkage thin film layer and then the coating is dried to obtain the heat sealing layer; and the BOPP heat shrinkage thin film layer and the polyacrylic ester layer are spliced by adopting transparent glue, so as to guarantee the binding force between the polyacrylic ester layer and the BOPP heat shrinkage thin film layer.
Description
technical field [0001] The invention belongs to the technical field of film production, and in particular relates to a wear-resistant cigarette packaging film and a production method thereof. Background technique [0002] Biaxially stretched plastic film is formed by special processing of physical, chemical, mechanical and other means. It is lower than the melting point of the film and higher than the glass transition temperature. A product made by heat setting treatment in a tight state. Biaxially oriented polypropylene (BOPP) films are made in this way. Due to the stretching of certain multiples in both vertical and horizontal directions, the molecular segment orientation and crystallinity are improved, so the tensile strength and tensile elastic modulus of the film can be significantly improved, and heat resistance, cold resistance and transparency can be improved. , air tightness and electrical insulation, etc. [0003] Cigarette packaging film is referred to as cigar...
