Abstract

The invention provides an anti-oxidation polyethylene heat shrinkable film with high tensile strength and preparing method thereof, by weight, comprising 60 - 80 parts of metallocene linear low density polyethylene, 30 - 40 parts of ethylene-octene copolymer, 25- 35 parts of liquorice root, 10 - 20 parts of nano-titanium dioxide, 6- 10 parts of epoxy vegetable oil, 4 - 6 parts of oleic acid amide, 3 - 5 parts of magnesium hydroxide, 2- 3 parts of antioxidant, and 1- 2 parts of heat stabilizer; the invention adopts the metallocene linear low density polyethylene and the ethylene-octene copolymer as the raw materials, which greatly enhances the heat sealability and strength of shrink film, and greatly improves the strength of the prepared film. The film is hard to break and has the outstanding puncture resistance, good age resistance and obvious shrinkage advantages, which can meet the processing performance and the physical and mechanical properties required by the high tensile strength of polyethylene film. And the film is in good shape.
