Waterproof environment-friendly packaging bag and preparation method

Abstract

The invention discloses a waterproof environment-friendly packaging bag and a preparation method, the waterproof environment-friendly packaging bag comprises a base layer, and the base layer comprises the following main components: water, rice husk, cellulose, starch, natural resin, lignin, a curing agent, a phosphate ceramic material and biodegradable plastic. The base layer is prepared from the rice husks, the cellulose, the starch, the natural resin, the lignin, the curing agent and other materials, so that the environment-friendly effect of the base layer can be greatly improved, and the base layer has a degradable function on the basis of improving the strength of the base layer; meanwhile, the phosphate ceramic material and the biodegradable plastic are wide in degradation range, can effectively improve the wear-resistant and waterproof effects of the packaging bag, are non-toxic to the environment, enable the base layer to form a scientific beneficial substance proportion, and solve the problems that an existing industrial transportation packaging bag is poor in waterproof effect, prone to being affected by external moisture in the use process and poor in waterproof performance. The sealing protection effect of the packaging bag is seriously disturbed, and the use requirement of a high-humidity environment cannot be met.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a waterproof environmental protection packaging bag and a preparation method. Background technique [0002] Packaging bags refer to bags used to package various supplies, so that the goods can be easily transported and stored in the process of production and circulation, and are widely used in daily life and industrial production. However, the existing industrial transportation packaging bags have poor waterproof effect. It is easily affected by external moisture during use, which seriously interferes with the sealing and protective effect of the packaging bag, and cannot meet the needs of high-humidity environments. SUMMARY OF THE INVENTION [0003] In order to solve the problems raised in the above background technology, the purpose of the present invention is to provide a waterproof environmental protection packaging bag and a preparation method, which have the advant...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a waterproof environmental protection packaging bag and its preparation method, which has the advantage of improving the waterproof effect, and solves the problem that the waterproof effect of the existing industrial transport packaging bags is relatively poor. It is easily affected by external moisture, which seriously interferes with the sealing and protection effect of the packaging bag, and cannot meet the needs of high-humidity environments.
