Aluminum film composited EPE (expandable polyethylene)

Abstract

The invention discloses aluminum film composited EPE (expandable polyethylene). The aluminum film composited EPE is formed by combining an aluminized film layer on the top layer, an adhesive on the middle layer and an EPE layer on the bottom layer, wherein the aluminized film layer is an aluminized PET (polyethylene terephthalate) film and accounts for 23%-44% of the total weight of the aluminum film composited EPE; the adhesive accounts for 10%-24% of the total weight of the aluminum film composited EPE; the EPE layer accounts for 44%-55% of the total weight of the aluminum film composited EPE. The aluminum film composited EPE has the advantages of excellent damping, shakeproof and mechanical properties, stiff and smooth performance, impact resistance, resistance to chemical corrosion, high transparency, good gloss and high strength.

Description

technical field [0001] The invention relates to an aluminum film composite pearl cotton. Background technique [0002] EPE pearl cotton is a new type of environmentally friendly packaging material, which is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene. It overcomes the shortcomings of ordinary styrofoam such as fragility, deformation, and poor recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. Good chemical resistance is an ideal substitute for traditional packaging materials, widely used in electronic appliances, instruments, computers, audio, medical equipment, industrial control chassis, hardware lighting, handicrafts, glass, ceramics, home appliances, spraying, furniture and furniture , alcohol and resin and other high-end fragile gift packagi...

AI Technical Summary

Problems solved by technology

Both packaging materials have their own advantages, but the single pearl cotton is not beautiful enough, and the single aluminum film limits its application field. The aluminum film is covered on the pearl cotton, which is widely used in electronic appliances, instruments, computers, audio, Packaging of various products such as medical equipment, industrial control cabinets, lighting, handicrafts, glass, ceramics, home appliances, spraying, furniture, wine and gift packaging, hardware products, toys, melons and fruits, inner packaging of leather shoes, daily necessities, etc.

Although the pearl cotton aluminum-clad film composite packaging material is beautiful, it often has the problem of weak bonding
