Abstract

The invention belongs to the technical field of printing film preparation, and discloses a polypropylene printing film preparation method of a high-strength abrasion resistant flower. A modified polypropylene film prepared by the polypropylene printing film preparation method of the high-strength abrasion resistant flower has excellent mechanical strength, vapor barrier property and food safety performance. The surfaces of a small number of polar monomers are grafted and modified, surface polarity and printability of a polypropylene material can be greatly improved, a critical condition of a supercritical carbon dioxide is 10MPa, pure supercritical carbon dioxide fluid has higher solubility, and a small number of polar monomers and initiators can be dissolved in the pure supercritical carbon dioxide fluid. The surface printability and scratch resistance of a printing layer of the polypropylene material can be improved when excellent comprehensive performance of the polypropylene material is kept.

Description

technical field [0001] The invention belongs to the technical field of printing film preparation, and in particular relates to a method for preparing a high-strength anti-friction polypropylene printing film. Background technique [0002] Printing lamination refers to mounting a transparent plastic film on paper products. A layer of transparent plastic film is mounted on the paper product, which is the lamination film. Specifically, if a protective film is required for parts that are prone to wear, such as the cover in the printing of the product manual and the outer surface of the carton, it must be laminated with a layer after printing and before folding and cutting. This film must be very transparent. It has good toughness, uniform texture, no sand holes, and a smooth surface. It is usually made of polypropylene material. It is also pre-coated with thermoplastic polymer adhesive to combine with paper. It sticks firmly to the paper. The result is a paper with a better g...
