Problems solved by technology

But it also has the following disadvantages: it is easy to be damaged, and the bubble chamber is easy to be crushed when it is stressed, and once the air cushion film is damaged or the bubble chamber is broken, it loses its efficacy
Moreover, if the inner lining is placed in the packaging body during use, the operation is cumbersome and the effect is not good

specific Embodiment approach

[0011] refer to figure 1 As shown, a kraft paper composite double-layer air cushion film includes a kraft paper layer 1, a foam film layer 2 on the surface of the kraft paper layer, and a composite plastic film 3 on the surface of the foam film layer to seal the airbag.

[0012] The production process is: firstly coat the rough surface of the paper with a film, then perform corona treatment, and use electric shock treatment to make the surface of the paper have higher adhesion, then compound the paper and foam film through a dry lamination process, cool and wind. , you can.

Abstract

The invention relates to a kraft compounded double-layer air bubble film, which comprises a kraft layer, a foaming film layer, and a film layer. The double-layer air bubble film effectively combines the conventional kraft and an air bubble film; the air bubble film provides the cushion function; and the whole packaging material has the effects of facilitating writing on the surface of an outer layer, being printed with various patterns and added with easy open strips on the surface of the outer layer, resisting shock and water, and preventing dampness. The weight of the packaging material is nearly not increased, the surface of the air bubble film with protruding bubbles is provided with a layer of plastic film to increase stressed areas of the bubbles so as to overcome a defect that a single air bag is easy to break after the surface of the prior air bubble film is stressed is over.

Description

technical field [0001] The invention relates to packaging materials for postal parcels, and more specifically relates to a kraft paper composite double-layer air cushion film. Background technique [0002] Traditional postal packaging bags are generally made of folded kraft paper and have waterproof function, but they cannot provide more protection for fragile items such as CDs, electronic components, integrated circuit boards, optical lenses, gifts, etc. That is, the shockproof function cannot be provided, and it is easy to damage the loaded items due to extrusion, collision, and drop. [0003] Air cushion film, also known as bubble film, is made of high-quality polyethylene resin. Because the air cushion film has an air bag filled with air, it is light, elastic, sound-proof, shock-proof and wear-resistant. It is a commonly used packaging at present. The material has a wide range of uses, and has the characteristics of waterproof, shockproof, moisture-proof, and compressio...
