Fiber toughened polyethylene wrapping film, and preparation method thereof

Abstract

The invention discloses a fiber toughened polyethylene wrapping film. The fiber toughened polyethylene wrapping film is composed of, by weight, 1 to 2 parts of sodium diacetate, 100 to 110 parts of linear low density polyethylene, 1 to 2 parts of p-aminobenzene sulfonic acid, 7 to 10 parts of aluminium isopropoxide, 2 to 3 parts of cyanoethyl cellulose, 3 to 5 parts of isopropyl palmitate, 4 to 6 parts of cellulose phosphate, 0.7 to 2 parts of polybenzimidazole, 4 to 6 parts of oxidized polyethlene wax, 0.1 to 0.2 part of methyl stannum mercaptide, 3 to 4 parts of diacetone alcohol, 0.2 to 0.6 part of dialkyl hydroquinone, 1 to 2 parts of alkanolamide, 2 to 3 parts of antimonous oxide, 0.4 to 1 part of isothiazolinone, 1 to 2 parts of calcium propionate, and 10 to 13 parts of diatomite. According to a preparation method, a plurality of kinds of fiber are added, so that the strength and toughness of the fiber toughened polyethylene wrapping film are increased greatly, broken is not easily caused, the fiber toughened polyethylene wrapping film possesses both low temperature resistance and high temperature resistance, application effect is excellent, no pollution is caused, and cost is application is reduced.

Description

technical field [0001] The invention relates to the field of stretch films, in particular to a fiber-toughened polyethylene stretch film and a preparation method thereof. Background technique [0002] Stretch film is mainly used for sales and transportation of various products. Its main function is to stabilize, cover and protect products. Therefore, stretch film must have high puncture resistance, good shrinkage and shrinkage stress. The initial stretch film was mainly PVC. With the continuous improvement of the performance requirements of the stretch film, the PVC stretch film gradually decreased, while various polyethylene stretch films developed rapidly. Polyethylene stretch film is a kind of material with good toughness, which is widely used in the packaging of alcohol, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, impact resistance, and Strong tear resistance, not easy to break, not afraid of moisture, large shrink...

AI Technical Summary

Problems solved by technology

[0003] The shrinkage temperature of the polyethylene stretch film produced by the prior art is generally higher, the energy consumption is large, the performance, thickness and strength of the product are not stable enough, and the functionality is relatively single. Therefore, a kind of high toughness and strong tear resistance is designed. Stretch film materials with certain antibacterial and waterproof properties can effectively promote the development of film applications.
