Abstract

The invention provides a polyethylene film with tensile strength. The polyethylene film is prepared from the following raw materials by weight: 15-25 parts of low-density polyethylene, 50-70 parts oflinear low-density polyethylene, 5-15 parts of metallocene polyethylene, 10-15 parts of polyethylene terephthalate, 3-7 parts of trimethylolpropane trimethacrylate, 5-12 parts of zinc stearate, 14-18parts of oxidized polyethylene wax, 12-16 parts of ammonium polyphosphate, 3-6 parts of nanometer silica, 1-4 parts of a silane coupling agent, 3-8 parts of glass fibers, 6-10 parts of an antioxidant168 and 0.2-0.4 part of an ultraviolet absorber 328. The polyethylene film with tensile strength has excellent strength, toughness and tensile resistance. The invention also provides a preparation method for the polyethylene film with tensile strength.

Description

technical field [0001] The invention belongs to the technical field of polyethylene materials, in particular to a stretch-resistant polyethylene film and a preparation method thereof. Background technique [0002] Plastic films, used for packaging and as laminations. Plastic packaging and plastic packaging products are taking an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields. [0003] Polyethylene film is a colorless, tasteless, odorless, translucent, non-toxic insulating material. It is widely used in packaging bags, food bags, and various containers. Polyethylene film has the characteristics of moisture resistance and low moisture permeability, but the existing polyethylene film for packaging needs to be improved in resilience and tensile strength. [0004] Metallocene polyethylene is a new type of thermoplastic. Metallocene polyolefin has better performance than the...
