Degradable high strength composite bubble film and processing method thereof

Abstract

The invention discloses a degradable high strength composite bubble film and a processing method thereof. The degradable high strength composite bubble film comprises a bubble film layer, reinforced layers, wear-resistant layers and flame-retardant layers. The bottom side of the bubble film layer is provided with a reinforced layer, a wear-resistant layer is arranged at the bottom side of the reinforced layer, a flame-retardant layer is arranged at the bottom side of the wear-resistant layer, and the top side of the bubble film layer is symmetrically equipped with a reinforced layer, a wear-resistant layer and a flame-retardant layer in order. A biodegradation additive is added to the bubble film with polyethylene as the matrix to improve the degradation speed, and at the same time, the externally used reinforced layers and wear-resistant layers are both organic matters, do not cause pollution, and also can increase the tensile strength and friction strength of the bubble film, which is not easily damaged during use, the setting of the flame-retardant layers can improve the high temperature resistance of the bubble film and achieve a better use effect. The making process adopted bythe invention is simple, and the product has market competitiveness and can bring better benefits.

Description

Technical field [0001] The invention relates to the technical field of bubble films, in particular to a degradable high-strength composite bubble film and a processing method thereof. Background technique [0002] The bubble film is made of high-pressure polyethylene as the main raw material, and then added with whitening agent, opening agent and other auxiliary materials, and extruded into bubbles at a high temperature of about 230 degrees. It is a kind of light texture, good transparency, non-toxic, A new type of odorless plastic packaging material, which can protect the product from moisture, cushion, and heat. It is also called bubble cushion. The existing bubble film has low strength and is easy to break and damage during extrusion and use, and has poor degradation ability. After use, it takes a long time to degrade, and the pollution generated during degradation is large, which damages the environment. Therefore, it is necessary to design a degradable high-strength composit...

Problems solved by technology

[0002] Bubble film is made of high-pressure polyethylene as the main raw material, and then added whitening agent, opening agent and other auxiliary materials, and is extruded and blistered into bubbles at a high temperature of about 230 degrees. It is a product with light texture, good transparency, non-toxic, A new type of odorless plastic packaging material, which can protect the product from moisture, cushioning, and heat preservation. It is also called an air bubble cushion. The existing air bubble film has low strength. It is easy to break and damage during extrusion and use, and its degradation ability is poor. After use, it takes a long time to degrade, and the pollution generated during the degradation is large, causing damage to the environment. Therefore, it is necessary to design a degradable high-strength composite air bubble film and its processing method.
