Degradable air bubble film and preparation process thereof

Abstract

The invention discloses a degradable air bubble film and a preparation process thereof. The invention relates to the technical field of packaging materials, in particular to the air bubble film, whichcomprises a base layer; the upper surface and the lower surface of the base layer are both fixedly connected with bubble film layers, the outer surfaces of the bubble film layers are provided with waterproof anti-fouling layers, and the base layer is a grid surface formed by weaving bamboo charcoal fibers, and the weight part is 60-70 parts. The invention discloses a degradable air bubble film and a preparation process thereof. The base layer and the two bubble film layers are bonded together; therefore, the film has excellent use strength; the outer surface of the air bubble film layer is coated with a waterproof anti-fouling layer; therefore, the characteristics of hydrophobicity and pollution resistance can be provided, and damage of water stains and dust to wrapped articles is reduced; and meanwhile, the biodegradable additive is added into the mixed components, so that the degradable air bubble film can be quickly degraded after being discarded, and the degradable air bubble filmis simple in manufacturing process and has market competitiveness, and better benefits can be brought.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, in particular to a degradable bubble film and a preparation process thereof. Background technique [0002] Bubble film, also known as air cushion film, air bead film, bubble cloth, bubble paper, bubble film, bubble film or air cushion film, is a chemical product used for packaging and filling, which is anti-pressure, moisture-proof and shock-proof. It has good shock absorption, Impact resistance, heat sealing, non-toxic, odorless, moisture-proof, corrosion-resistant, good transparency and other advantages. [0003] Existing packaging bags, packaging films, bubble bags or bubble films are usually petroleum-based products, which consume a large amount of petroleum, which is one of the main factors for excessive carbon emissions, causing endless "white pollution". Difficult to degrade, easy to cause adverse effects on the environment, does not meet environmental protection standards, an...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a degradable air bubble film and its preparation process, which solves the problem that the ordinary air bubble film is not only difficult to degrade after being discarded, but also easily causes adverse effects on the environment and does not meet the environmental protection standards. , and the waterproof, stain resistance and strength are poor, making the protected items vulnerable to water and dust pollution, and also vulnerable to external shocks, making the problem of poor practicability
