Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the following embodiments are specifically illustrated with reference to the accompanying drawings.

< Structure I >

As shown in fig. 1, the bubble composite film includes a base film layer 11 and a first PE film layer 12, the first PE film layer 12 covers the base film layer 11, and a plurality of bubbles 13 are uniformly disposed between the first PE film layer 12 and the base film layer 11. As shown in fig. 2, the base film layer 11 includes a PA (polyamide) or PET film layer 111, and a second PE film layer 112 covering the PA or PET film layer 111. In this embodiment, the second PE film layer 112 is bonded to the PA or PET film layer 111 by using a solvent-free glue, or a layer of the second PE film layer 112 is sprayed on the PA or PET film layer 111 by using a film spraying technique, or a seven-layer or nine-layer co-extruded film forming base film layer of PA or PET and PE is obtained by using a co-extrusion method. The first PE film layer 12 overlies the second PE film layer 112. The first PE film layer 12 is bonded to the second PE film layer 112 by heat and pressure. In the present embodiment, a cast film technique is used to coat the base film layer 11 with a PE cast film on the second PE film layer 112 side.

As shown in fig. 3, 4, and 5, the shape of the bubble is a diamond shape, a square shape, or a hexagonal shape. The air bubbles 13 between the first PE film layer 12 and the base film layer 11 are arranged in the form of a matrix. Each bubble 13 has a length l of 5mm to 10mm, a width d of 5mm to 10mm, and a height h of 0.2mm to 2 mm. The distance between two adjacent bubbles is 0.5mm-1 mm. The height of the bubbles is too low, and the formed bubble composite membrane has insufficient softness and cannot play a corresponding role; the height of the bubbles is too high, and the bubbles are easily crushed, so that the bubble composite membrane loses due effect. The air bubbles formed by the length and the width in the air bubble composite membrane and the space between the air bubbles enable the performance of the air bubble composite membrane to be better, and the air bubble composite membrane cannot achieve due softness when the length and the width of the air bubbles and the distance between the air bubbles are too large or too small.

In this embodiment, the bubbles 13 are a plurality of uniformly arranged bubbles formed between the base film layer 11 and the first PE film layer 12 after the base film layer 11 is preheated by the heating roller, and then the bubbles are formed on the base film layer 11 by the bubble roller, and finally a PE casting film is cast on the second PE film layer 112 surface of the base film layer 11.

< Structure two >

As shown in fig. 6, the vacuum compression bag 100 includes: a pouch body 10, a sealing unit 20, and an air suction valve 30. One end of the bag body 10 is open, and the bag body 10 is made of a bubble composite film in the structure I. The sealing unit 20 is disposed inside the open end of the bag body 10. The air valve 30 is installed on the bag body 10 and is communicated with the inner cavity of the bag body 10.

In this embodiment, the first PE film layer 12 is an inner side of the bag body 10.

The sealing unit 20 is used to seal the mouth of the bag body 10. The sealing unit 20 includes: two parallel arrangement's clip chain, every clip chain all includes can closely cooperate sand grip and concave strip.

In this embodiment, the vacuum compression bag further comprises a slider detachably mounted at the open end of the bag body 10 for tightly fitting the two pairs of convex and concave strips of the sealing unit 20 together, thereby sealing the bag body 10.

The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
