Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1, the anti-pollution air-inflation packaging composite film comprises a puncture-resistant layer 1, a barrier layer 2 and a heat-sealing layer 3 which are sequentially compounded, wherein the puncture-resistant layer 1 is arranged in the middle of the barrier layer 2 in the extension direction, and a long-edge heat-sealing gap 21 is reserved in the width direction of the barrier layer 2 and is used for sealing edges of subsequent films after the films are directly attached to each other in opposite directions to form an independent air-inflation package.

In the present embodiment, the first and second electrodes are,

the puncture-resistant layer 1 is made of non-woven fabrics and is compounded on the surface of the barrier layer 2 in a wet mode, compared with a plastic film, the puncture-resistant layer is more puncture-resistant and wear-resistant, has higher strength and can shield light to a certain degree, and after the manufactured bag body is inflated, the bag body is directly placed in an environment with gravels and the like and is extruded, the bag body is also prevented from being scratched easily;
