Problems solved by technology

[0003] In the field of packaging materials in the pharmaceutical, food and other industries, although PE films are widely used, because PE films cannot provide a good barrier to oxygen and water vapor, and the antibacterial effect is poor, the development of PE films is restricted. PE film with good antibacterial performance has important market value and social value

Abstract

The invention discloses a PE film having excellent barrier performance and being antibacterial, which is prepared from, by weight, 90-100 parts of low density polyethylene, 15-20 parts of metallocenelinear low density polyethylene, 23-26 parts of maleic amide grafted polyethylene, 18-22 parts of polyvinylpyrrolidone, 1-2 parts of glycerol monostearate, 2-5 parts of polyglycerol fatty acid ester,1.3-1.7 parts of an antioxidant, 1.0-1.5 parts of a sterilizing agent, 0.4-0.8 parts of oleamide, 0.6-1.0 part of calcium naphthenate, and 0.9-1.3 parts of modified diatomite. The invention also discloses a preparation method of the PE film having excellent barrier performance and being antibacterial. The PE film has excellent barrier performance and antibacterial performance, can be widely applied to package materials in the fields of medicines, foods and the like. The invention can promote development of the PE films.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a PE film with excellent barrier performance and antibacterial properties and a preparation method thereof. Background technique [0002] Polyethylene (referred to as PE) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100 ° C ~ -70 ° C), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation) nature of the acid). It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation, so it is widely used in various industries. Polyethylene film is the most widely used polymer material in the world today. PE protective film is based on s...
