Problems solved by technology

Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, retort food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. However, at present, with the application of plastic films more and more widely, various Additive ingredients, including toxic plasticizers, will cause the plastic film to release toxic gas when it is burned at high temperature, which will seriously affect human health. At the same time, it is not easy to degrade and pollute the environment.

Abstract

The invention discloses an environment-friendly plastic film, which is prepared from the following raw materials in parts by weight: 140 to 180 parts of a pretreated base material, 3 to 5 parts of diphenyl silanediol, 1 to 2 parts of zinc pyrithione, 2 to 4 parts of melamine, 0.3 to 1 part of fatty acid diethanolamide and 40 to 50 parts of antibacterial filler emulsion. According to the invention,the filler is high in strength and good in surface activity, can improve the surface mechanical property of a finished film, and has good compatibility with a polypropylene matrix; and the uniform stability of the finished film is good, and the film further has good antibacterial performance and excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an environment-friendly plastic film and a preparation method thereof. Background technique [0002] Plastic films, ie films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, are used for packaging and as laminations. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, retort food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. However, at present, with the application of plastic films more and more widely, various Additive ingredients include toxic plasticizers, which cause the plastic film to release...
