Abstract

The invention discloses a high-strength antistatic polyethylene film. The polyethylene film contains the following components in percentage by weight: 15-35% of low-density polyethylene, 50-70% of linear low-density polyethylene, 5-15% of metallocene polyethylene, 1-4% of an anti-blocking agent, and 1-3% of an antistatic agent. Besides, the invention also discloses a preparation method and application of the high-strength antistatic polyethylene film. The high-strength antistatic polyethylene film provided by the invention is prepared by the steps of taking the low-density polyethylene (LDPE) as a base material, adding the linear low-density polyethylene (LLDPE) and the metallocene polyethylene (MLLPE) and performing blending extrusion, granulation and blow molding, so that the polyethylene film has relatively good tensile strength and antistatic property; and a packaging bag prepared from the high-strength antistatic polyethylene film has the characteristics of good economical efficiency and mechanical property, lasting antistatic property and convenience in use.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-strength antistatic polyethylene film and its preparation method and application. Background technique [0002] The packaging of commodities plays an important role in the storage, quality assurance, transportation and beautification of commodities. With the development of the economy, the advancement of science and technology, the ever-changing products, and the fact that people's life tends to be more convenient and leisure, there are higher requirements for product packaging. [0003] With the development of industrialization, office electronic equipment is also developing in a more and more sophisticated direction. The traditional outer packaging in this industry is packed in cartons, but the cartons are poor in moisture resistance, the packaging is prone to mold, and the cartons are prone to friction with the surface of the equipment. It affects...
