Abstract

The invention discloses a PE thin film packaging material and a preparation method thereof, and belongs to the technical field of thin film material preparation. The PE thin film packaging material isprepared from the following raw materials: PE resin, nano-SiO2, sodium dodecylbenzenesulfonate, alpha-cyanoacrylate, aluminum isopropoxide, potassium trimethylsilanolate, polyethylene oxide, zinc stearate, glycerol, montmorillonite, oleic acid, polyethylenimine. The PE thin film packaging material is prepared by the steps such as grinding, high temperature reaction, mixing, granulation, rolling and the like. With a process of the invention, the tensile strength, elongation at break, and tear strength of the PE thin film packaging material can be improved.

Description

technical field [0001] The invention belongs to the technical field of film material preparation, and in particular relates to a 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 tran...
