Matt polyethylene film suitable for intaglio printing and preparation process thereof

Abstract

The invention relates to a matt polyethylene film suitable for intaglio printing and a preparation process thereof, and belongs to the technical field of packaging, wherein the matt polyethylene film comprises an outer layer, a middle layer and an inner layer which are prepared by an intaglio printing process and are connected in sequence; the outer layer comprises 97.5 parts by mass of low density polyethylene, 1.5 parts by mass of a processing aid and 1 part by mass of a slipping agent; the middle layer comprises 100 parts by mass of low density polyethylene; and the inner layer comprises 98.5 parts by mass of low-density polyethylene, 1 part by mass of a processing aid and 0.5 part by mass of a slipping agent. The inner layer is made of resin with the grade of FB2230, so that the surface glossiness is effectively improved, and the extinction effect is achieved; and the resin is enhanced polyethylene resin, has higher heat sealing strength, is easier for bag making, and does not generate the bad problems of knife sticking, wire rising and the like.

Description

technical field [0001] The invention relates to the field of hygiene material packaging, in particular to a matting polyethylene film suitable for gravure printing and a preparation process thereof. Background technique [0002] In the sanitary material packaging industry, various packaging materials and different printing patterns attract consumers. However, with the change of people's consumption concept and the improvement of the pursuit of quality of life, the requirements for packaging grades have also changed. [0003] From the original single-layer inner printing structure of the hygiene material packaging to the composite film structure, the key to the safety of the content of the manufacturer is the emphasis on consumer safety. The packaging structure has made a qualitative leap, so it is widely favored by consumers. Therefore, the brand awareness, reputation and reputation of the manufacturer are also concerned by people. [0004] In the printing industry, polye...

AI Technical Summary

Problems solved by technology

[0004] In the printing industry, polyethylene gravure printing is a headache printing material for major enterprises. Compared with ordinary double-drawn polyester, double-drawn nylon and double-drawn polypropylene printing films, polyethylene printing has a higher degree of difficulty and higher color registration accuracy. Poor printing quality problems plague the industry elite

[0005] The existing common matting film is PE with matting effect on the surface formed by mixing various resins in proportion, but the matting of this kind of matting PE film is generally (mainly measured by surface gloss and haze index) and the film surface is rough , and some even produce chapped lines, which affect the physical properties of PE film, printing color registration, etc.
