Novel degradable high-strength air bubble film processing technology and processing equipment thereof

Abstract

The invention discloses a novel degradable high-strength air bubble film processing technology and processing equipment thereof. The processing equipment comprises a frame body, an adsorption barrel, a water coating device, a film pressing device, a vacuum adsorption bin, a vacuum pipe, an upper-layer film roller and a lower-layer film roller. The air bubble film has the advantages that the air bubble film is manufactured through polyvinyl alcohol, water is added between two layers of polyvinyl alcohol films to serve as an adhesive, the air bubble film is obtained through low-temperature heating and bonding, the air bubble film is high in strength and degradable and can be recycled for redissolution and reutilization, the lower layer film can be better adsorbed through heating of the adsorption cylinder, and a cavity is formed; the device can prevent incomplete formation of a cavity, an upper-layer film can be uniformly coated with water through a water coating device, redundant water and water drops on the upper-layer film can be cleaned through a coating roller, the redundant water can be prevented from remaining in an air bubble film, and a vacuum adsorption bin can adsorb the position where a lower-layer film needs to be adsorbed. And the problem of incomplete formation of a lower-layer membrane cavity caused by large air inlet quantity of other parts during comprehensive adsorption can be prevented.

Description

technical field [0001] The invention relates to the technical field of bubble film processing, in particular to a novel degradable high-strength bubble film processing technology and processing equipment. Background technique [0002] Bubble film is a new type of plastic packaging material that is light in texture, good in transparency, non-toxic and odorless. It can prevent moisture, buffer and heat preservation of products. The traditional bubble film is polyethylene bubble film, which is non-degradable and easy to discard. adversely affect the environment; [0003] In addition, the polyethylene bubble film needs to be granulated for recycling. During the granulation process, gas that pollutes the environment will be generated, which is not conducive to the protection of the environment, and the traditional bubble film needs to be glued with an adhesive during the bonding process.

Problems solved by technology

[0002] Bubble film is a new type of plastic packaging material with light texture, good transparency, non-toxic and odorless, which can protect the product from moisture, buffer, and heat preservation. The traditional bubble film is made of polyethylene bubble film, which is non-degradable and easy to discard. adverse impact on the environment;

[0003] In addition, polyethylene bubble film needs to be granulated during recycling, which will produce gas that pollutes the environment during the granulation process, which is not conducive to environmental protection, and the traditional bubble film needs to be glued with adhesives during the bonding process. Bubbles are formed, and a large amount of practical adhesives will also cause environmental pollution, and the traditional bubble film needs a higher temperature to heat the film during processing, which is easy to modify the film, and it is easy to cause the strength of the bubble film to be different from that of the film. Reduced toughness
