Problems solved by technology

[0003] However, the stability of plastic film materials is poor, and it will decompose under the action of heat and light, and its mechanical strength will also decrease. As far as food packaging is concerned, long-term use will affect human health and cannot meet the requirements of sterility. Limits the scope of application of plastic film materials

Abstract

The invention discloses a high-tenacity PS film for packaging and a preparation method thereof. A packaging material is prepared from, by weight, 120-220 parts of PS resin, 1-8 parts of polymethylphenyl siloxane fluid, 2-15 parts of dicyclohexyl phthalate, 1-6 parts of epoxy tetrachloro phthalic acid ester, 3-12 parts of phosphite ester, 4-9 parts of nitrile rubber, 0.5-6 parts of oxidized polyethlene wax, 0.3-2 parts of microcrystalline wax and 0.4-5 parts of a calcium-zinc stabilizer. The PS film packaging material has the good tenacity and mechanical property, and meanwhile the method is simple in technology, easy to repeatedly implement and applicable to various packaging machines.

Description

technical field [0001] The invention belongs to the field of packaging materials, in particular to a high-toughness PS film for packaging and a preparation method thereof. Background technique [0002] Films made of polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS (acrylic-butadiene-styrene), and other resins 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, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. [0003] However, the stability of plastic film materials is poor, and it will decompose under the action of heat and light, and its mechanical strength will also decreas...
