Novel composite aluminum membrane-air bubble film

Abstract

The invention discloses a novel composite aluminum membrane-air bubble film packaging material. The material is prepared by compounding an air bubble film and an aluminum membrane through tape casting of a coating layer which is obtained by mixing an adhesive and a low density polyethylene resin particle, wherein an upper layer is the aluminum membrane, a lower layer is the air bubble film, another layer of the aluminum membrane can be compounded below the air bubble film through tape casting of a coating material of the coating layer, the usage amount of the low density polyethylene resin particle accounts for 25 to 35% of the weight of the coating material, the thickness of the aluminum membrane is 8 to 25 mu m, and the diameter of an air bubble body of the air bubble film is 3 to 30 mm. Since the low density polyethylene resin particle is cheaper than the adhesive, the novel composite aluminum membrane-air bubble film packaging material provided by the invention has reduced production cost while the compounding quality of the air bubble film and the aluminum membrane is ensured.

Description

technical field [0001] The invention belongs to the technical field of packaging materials and relates to a composite packaging material, in particular to a novel composite aluminum film bubble film. Background technique [0002] Bubble film (Air Bubble Film) is also known as air cushion film, air bead film, bubble cloth, bubble paper, bubble film, bubble film, air cushion film. It is a pressure-proof, moisture-proof and shock-proof chemical product used for packaging filling. It has the advantages of good shock absorption, impact resistance, heat sealing, non-toxic, odorless, moisture-proof, corrosion-resistant, and good transparency. It is a product made of high-pressure polyethylene as the main raw material, adding whitening agent, anti-blocking agent and other auxiliary materials, and extruding and blistering into bubbles at a high temperature of about 230 degrees. It is a new type of plastic packaging material with light texture, good transparency, non-toxic and odorl...

AI Technical Summary

Problems solved by technology

[0005] A single air bubble film and aluminum film both limit their respective application ranges, and the two can be used in combination. However, coating materials such as adhesives need to be used in the process of casting and compounding the aluminum film and the air bubble film. Due to the high price of the adhesive, Makes the cost of composite aluminum film bubble film packaging materials relatively high
