Abstract

The invention discloses an environmentally-friendly shopping paper bag water-proof outer film, and relates to the technical field of plastic films. The environmentally-friendly shopping paper bag water-proof outer film is prepared from the following raw materials in parts by weight: 35-40 parts of low-density polyethylene, 10-15 parts of polypropylene, 6-10 parts of hydrogenated rosin, 6-10 parts of chitosan, 5-8 parts of filling mineral powder, 5-8 parts of hydrogenated castor oil, 4-6 parts of soybean protein gel, 4-6 parts of rice bran wax, 3-5 parts of sodium carboxymethyl starch, 2-3 parts of glyceryl stearate, 2-3 parts of polyether, 1-2 parts of butadiene rubber, 1-2 parts of microcrystalline wax, 0.5-1 part of urea and 0.5-1 part of antimonous oxide. The environmentally-friendly shopping paper bag water-proof outer film can be attached to the outside of a shopping bag to make an environmentally-friendly shopping bag, so that the water resistance, aging resistance and mechanical performance of the shopping bag are improved, and the problems of tendency to breakage and moisture absorption due to use of paper bags are solved; moreover, the film is biodegradable, so that environmental pollution caused by use of the plastic bag is avoided.

Description

Technical field: [0001] The invention relates to the technical field of plastic films, in particular to an environment-friendly waterproof outer film of shopping paper bags. Background technique: [0002] In recent years, in order to reduce environmental pollution, people have gradually begun to use paper bags when shopping in shopping malls. Although paper bags are more environmentally friendly than plastic bags, they are easily damaged and cannot be used normally after being exposed to water and absorbing moisture. In order to solve this problem, our company has developed an environmentally friendly shopping paper bag waterproof outer film, that is, a layer of plastic outer film is attached to the outside of the paper bag, so as to improve the waterproof and lifting performance of the shopping paper bag, which can be used repeatedly. Moreover, the plastic outer film is biodegradable to avoid environmental pollution. Invention content: [0003] The technical problem to ...
