Problems solved by technology

Polyvinyl chloride, referred to as PVC, is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It has good mechanical properties and is widely used in the packaging of cooked food products, but the stability of PVC material is poor. It will decompose under the action of heat and light, and the mechanical strength will also decrease. As food packaging, long-term use will affect human health and cannot meet the requirements of sterility. These limit the scope of application of PVC material films

Abstract

The invention discloses a scratch-resistant PE (polyethylene) film packaging material and a preparation method thereof. The packaging material is prepared from the following components in parts by weight: 50-80 parts of PE resin, 15-30 parts of polyvinyl alcohol, 2-10 parts of scratch-resistant agent, 1-5 parts of zinc stearate, 0.5-2 parts of vinyl bis stearamide and 0.5-2 parts of glycerol. The prepared PE film packaging material has the advantages of favorable scratch resistance and favorable mechanical properties. The method is simple in technique, easy to repeat and applicable to various packaging machines.

Description

technical field [0001] The invention belongs to the field of packaging materials, in particular to a scratch-resistant PE film packaging material and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people are paying more and more attention to the quality of life. While there are many requirements for product performance, the packaging and appearance of products are also getting higher and higher. When people choose products, product packaging The quality and appearance of the product have also become a very important consideration for people to choose products and judge product quality. [0003] At present, the outer packaging film materials on the market usually use ethylene as the raw material, the most common of which is polyvinyl chloride. Polyvinyl chloride, referred to as PVC, is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It has good mechanical propert...
