Embodiment 1～6

[0062] Embodiments 1 to 6 provide a PE film, the raw material composition of which is shown in Table 1.

[0063] Table 1 Raw material composition of outer layer, middle layer and inner layer of PE film (parts by weight)

[0064]

[0065] The preparation method of the PE film of embodiment 1~6 is:

[0066] S1. Mix the raw materials of the outer layer, the middle layer and the inner layer of the PE film according to the proportions, add them to the extruder respectively, and then extrude and granulate to obtain the outer layer pellets, the middle layer pellets and the inner layer pellets;

[0067] S2. The outer layer pellets, the middle layer pellets, and the inner layer pellets are respectively added to the three-layer co-extrusion blown film machine, melt-extruded through the three-layer co-extrusion process, and subjected to inflation and traction, cooling, and corona treatment. , film winding to prepare the high-performance PE film;

[0068] The conditions of corona tre...

Abstract

The present invention disclosed a high -performance PE film and its preparation methods and applications.The high -performance PE film of the present invention includes the outer, middle and inner layers, where the outer layer is made from the following raw materials: low -density polyethylene, linear low -density polyethylene, luminous metal linear low -density polyethylene, polyolefin elastic body,Polymer metamorphosis stabilizer, light shielding agent, organic opening agent; the polymer quantum lumic stabilizer is a piperpheate glycolic polymer, a pyrine pyrium hydroxyl acrocyrium pyrineOne or more of the piopylramine -pyrium pyrium pyrium pyrium pyrium pyrine; the inner layer is made by the following raw materials: low -density polyethylene, linear low -density polyethylene, luminous metal linear low -density polyethylene, inorganic opening agent.The high -performance PE film of the present invention has excellent aging resistance and thermal resistance, and when printed by water -based ink, the drying rate is fast, and there will be no anti -adhesion after fake drying.

Description

technical field [0001] The invention relates to the technical field of plastic films, and more particularly, to a high-performance PE film and a preparation method and application thereof. Background technique [0002] Polyethylene (PE) is the variety with the largest output and the widest range of applications among general-purpose resins. The polyethylene film made from PE is used as a packaging film and a protective film to protect the packaged products during production, processing, transportation, storage and use. Free from contamination, corrosion and scratches. However, due to the disadvantages of low strength, poor heat resistance and poor aging resistance of PE film material itself, its application has been limited to a certain extent. Especially after being stored in a high temperature environment for a period of time, the PE film is easy to age, the material becomes brittle, the color turns yellow, and curls and deforms, which seriously affects its service life. ...
