Abstract

The invention discloses a PE film packaging material and a preparation method thereof. The PE film packaging material is prepared from the following components by weight: 50-80 parts of a PE resin, 25-30 parts of polyethylene oxide, 10-25 parts of zinc stearate, 8-12 parts of glycerol, 5-8 parts of montmorillonite, 3-8 parts of oleic acid and 2-4 parts of polyethylenimine. The PE film packaging material prepared by the method provided by the invention has good ink adhesive force and pigment adhesive force without surface treatment, is not easy to fall off, and has good glossiness and good tensile property.

Description

technical field [0001] The invention belongs to the field of film materials, in particular to a PE film packaging material and a preparation method thereof. Background technique [0002] Polyethylene film is a film with good mechanical properties. It is glossy and soft. It is generally formed by blow molding and casting processes. Polyethylene has good chemical stability, water resistance and scratch resistance. Therefore, it is one of the widely used packaging film materials. [0003] Existing packaging materials, in addition to having good mechanical properties and surface properties, also need to have good printing performance, be able to be well adhered to ink and pigment, and not easy to fall off, many existing packaging materials need to be surface-coated Processing is required to attach the picture to the surface of the film with ink and glue. [0004] Since polyethylene molecules do not contain polar groups and have high crystallinity, the surface printing perform...
