A high-barrier low-density polyethylene film and its preparation method

Abstract

This application relates to the technical field of polyethylene films, specifically disclosing a high-barrier low-density polyethylene film and its preparation method. A high-barrier low-density polyethylene film comprises the following raw materials in parts by weight: 100-130 parts of low-density polyethylene, 5-13 parts of high-density polyethylene, 15-25 parts of modified nano-alumina, 3-10 parts of sodium octyl dithiocarbamate, and 0.5-1 parts of antioxidant. The polyethylene film of this application can be used for product packaging and has the advantages of high strength and toughness, and high barrier properties.
