Abstract

The invention discloses a polyethylene foamed packaging film and a processing method thereof. The polyethylene foamed packaging film is characterized by comprising a high polymer layer I, a foaming layer, a high polymer layer II, a metal composite layer and a partition layer in sequence, wherein the high polymer layer is made of a PET12 material; the foamed layer is made of an EPE147 material; the high polymer layer is made of the PET12 material; the metal composite layer is an aluminum foil layer made of an AL12 material; the partition layer is made of a PEY45 material. The polyethylene foamed packaging film is of a five-layer structure, the quality performance of the polyethylene foamed film is greatly improved, the high polymer layer I is combined with the partition layer after being combined with the foamed layer, the high polymer layer II and the metal composite layer in a processing process, and finally total compounding is peformed, so that the quality performance of the polyethylene foamed film is improved, and the flexibility, the mechanical strength, the surface strength and the surface evenness of the polyethylene foamed film are improved.

Description

[0001] technical field [0002] The invention relates to the processing field of packaging films, in particular to a polyethylene foam packaging film and a processing method thereof. Background technique [0003] With the improvement of consumers' awareness of health and environmental protection, they pay more and more attention to the packaging materials of products. Foam packaging film is one of many packaging film products. During the processing of the existing foam packaging film, the compounding of the multi-layer structure is difficult to control, resulting in unsatisfactory stretchability, mechanical strength, surface strength and surface smoothness, and the product quality needs to be improved. Contents of the invention [0004] The purpose of the present invention is to provide a polyethylene foam packaging film with stable process, good quality and high strength, aiming at defects such as unsatisfactory flexibility, mechanical strength, surface strength an...
