Scraping-resistant PE film packing material and preparing method thereof

Abstract

The invention relates to a scraping-resistant PE film packing material.The scraping-resistant PE film packing material comprises, by mass, 78%-88% of high density polyethylene (HDPE), 9%-16% of low density polyethylene (LDPE), 1%-3% of scraping-resistant agent and 1.2%-3% of slipping agent.A preparing method of the scraping-resistant PE film packing material includes the following steps that the high density polyethylene (HDPE), the low density polyethylene (LDPE), the scraping-resistant agent and the slipping agent are mixed on a mixing machine according to the mass percent, added into a film blowing unit and heated and extruded through a film-blowing extruding machine, quick cooling is carried out in an air cooling mode during extruding, the product is subjected to the blowing rising process, the drawing process and the rolling process, and the scraping-resistant PE film packing material is obtained.Compared with the prior art, as the specific raw materials are adopted, the transparency of the raw materials is high, the high transparency effect and the scraping-resistant effect of the film can be achieved, and the HAZE can be 10 or below.

Description

[technical field] [0001] The invention belongs to the technical 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. At present, the outer packaging film materials on the market usually use polyvinyl chloride as the raw material. Polyvinyl chloride is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It has good mechanical properties and is widely used in packaging. However, its high ...

Problems solved by technology

At present, the outer packaging film materials on the market usually use polyvinyl chloride as the raw material. Polyvinyl chloride is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It has good mechanical properties and is widely used in packaging. However, its high transparency and scratch resistance are poor, and its haze (HAZE) is high, and the packaging material will decompose under the action of heat and light, and its mechanical strength will also decrease. As food packaging, long-term Use will have an impact on human health
