specific Embodiment approach

[0012] refer to figure 1 As shown, an EPE composite double-layer air-cushion film comprises an EPE layer 1, an air-cushion film layer 2 compounded on the EPE, and a PE layer 3 compounded on the air-cushion film.

[0013] The EPE layer 1 and the PE layer 3 are respectively compounded on the two layers of the air cushion film. The EPE layer 1 is compounded on the bottom air-sealing plastic film of the air cushion film airtight airbag, and the PE layer 3 is compounded on the surface of the air cushion film airtight airbag.

[0014] EPE layer 1, air-cushion film layer 2, and film layer 3 have the same or similar polarities, and are compounded in a hot-melt manner.

[0015] That is to say, when the traditional method is used to prepare the double-layer air cushion film, it is dry compounded with the EPE layer, rolled up, and obtained.

Abstract

The invention discloses an EPE compounded double-layer air bubble film, which comprises an EPE layer, and is characterized by also comprising an air bubble film layer compounded on the EPE and a film layer compounded on the air bubble film. The EPE layer and the film layer are respectively compounded on two layer surfaces of the air bubble film. The EPE compounded double-layer air bubble film has soft surface, can protect the integrity of the surfaces of packing materials from generating scratches, has shockproof, dampproof and waterproof functions, and can be used for packaging fragile objects; and the film layer is compounded on the surface layer of an enclosed air bag of the air bubble film so as to increase the pressure resistance of the air bag.

Description

technical field [0001] The invention relates to an EPE composite double-layer air cushion film and belongs to the field of packaging materials. Background technique [0002] EPE (Expandable polyethylene), also known as pearl cotton, is a new type of flexible packaging material popular in the international market today. It has high-strength cushioning, anti-vibration capabilities, softness, light weight, and high elasticity. , has the advantages of heat preservation, moisture resistance, friction resistance, corrosion resistance, etc. This product is widely used in various electrical appliances, electronics (semiconductors, televisions, refrigerators, computers, mobile phones, etc.), precision instruments, high-end furniture, leather shoes and various Packaging of various fragile products (various lighting, high-grade porcelain, etc.). However, it has shortcomings such as easy deformation, damage, and poor toughness, which need to be improved. [0003] Air cushion film, als...
