Abstract

The invention relates to the technical field of polyethylene film processing, and discloses a polyethylene film composition, polyethylene film, composite film and application thereof. The compositionincludes a first extrusion layer material, a second extrusion layer material, and a third extrusion layer material. Each of the first extrusion layer material, the second extrusion layer material, andthe third extrusion layer material contains multi-carbon copolymerized polyethylene which is a C4-C8 copolymerized polyethylene. The polyethylene film and the composite film containing the composition have excellent properties such as excellent puncture resistance, excellent barrier properties, low odor, and easy recycling.

Description

technical field [0001] The invention relates to the technical field of polyethylene film processing, in particular to a biaxially stretched polyethylene film BOPE composition, a biaxially stretched polyethylene film, a composite film and applications thereof. Background technique [0002] Materials are the material basis of human production. Polymer materials are widely used in the packaging industry to prevent the penetration of oxygen, water vapor, and carbon dioxide to keep food, fruits, and vegetables fresh. China is a big country in the production and manufacture of plastic packaging films. According to Ruoyi's statistics, in 2018, the output of biaxially oriented polypropylene (BOPP) packaging film in China was nearly 3.8 million tons; the output of cast polyethylene (CPE) packaging film was nearly 120,000 tons, and CPE has grown at a compound annual growth rate of 5% in recent years. increment. With the improvement of people's living standards and the diversificatio...
