As the air flow increases, space B begins to expand gradually. When the inflation is stopped, the gap between 2a and 2b, due to the special properties of the inner surface of the film itself Automatic adsorption together, plus the effect of air pressure, make the sticking between 2a and 2b tighter, so that the incoming air cannot leak out from B, and realize the film self-adhesive adsorption one-way leak-proof Functional technological invention.

2. The second content of the present invention: the fourth heat seal c1 and the fifth heat seal c2 form the air distribution and supply manifold A, and the top ends of the fourth heat seal c1 and the fifth heat seal c2 are in contact with the third heat seal b, and jointly Form a seal, the air enters from the opening, and flows into each space B from the false heat seal b1 through the channel a, so that when inflating, as long as the air source is directly connected to the opening of the distribution supply pipe A, the air will pass through b1 and a The split flow automatically enters each air chamber B, which is very convenient and fast when using the product, and greatly improves the work efficiency.

3. The third content of the present invention: the realization of the false heat seal b1. The heat seal of the fifth heat seal c2 directly acts on the high temperature resistant anti-adhesive printing barrier device d, the first layer of resin film 1 and the second layer of resin film 2a are heat sealed together by the effect of the fifth heat seal c2, while the fourth The first layer of resin film 3 and the third layer of resin film 2b are heat-sealed together through the effect of the fifth heat seal c2, wherein the inner surface of the second layer of resin film 2a is partially provided with a special high temperature resistant anti-adhesive printing barrier device d, which is to the self-adhesive film The raw material performance index itself is relatively high, and the inner surface of 2a needs to undergo a series of treatment such as corona during printing, and there are also very special professional requirements for the printing medium, which must be able to achieve the second A false heat seal is formed between the first layer of resin film 2a and the third layer of resin film 2b, so as not to make 2a and 2b stick together. 2a and 2b are separated by a special printing blocking device, so that the false heat seal b1 is realized, and the air can easily enter the space B.

For example, the U-shaped self-adhesive film repelling air three-dimensional packaging bag produced by utilizing the above principles. Its characteristics are: it is composed of the first layer of resin film 1, the fourth layer of resin film 3, two relatively wide resin films, the second layer of resin film 2a, and the third layer of resin film 2b, two narrow resin films, of which 2a Part of the inner surface is equipped with a special high temperature resistant anti-sticking printing barrier device, which has high requirements on the raw material performance index of the self-adhesive film itself, and the inner surface of 2a needs to undergo a series of treatments such as corona during printing. There are also very special professional requirements, which must be able to form a false heat seal between 2a and 2b during heat sealing, so as not to make 2a and 2b stick together. The first layer of resin film 1 and the fourth layer of resin film 3 are placed on the upper and lower surface layers, and the second layer of resin film 2a and the third layer of resin film 2b are placed in the middle layer.

Detailed ways

The self-adhesive air-repelling three-dimensional packaging material and its manufacturing method will be further described in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 below.

1. As long as there are four layers of resin film, using the principle of automatic adsorption of self-adhesive film and the barrier properties of special high-temperature resistant anti-stick printing barrier device, it can be produced through a series of simple local heat-sealing and bonding of special special-purpose heat-sealing equipment A series of related products from mucous membrane repelling air three-dimensional packaging materials.

As shown in Figure 4, take two polyethylene films of comparable size, one is composed of two narrower polyethylene self-adhesive films with mutual self-absorption, and two wider resin films are the first layer of resin film. 1. The fourth layer of resin film 3 is placed on the upper and lower surface layers respectively, the second layer of resin film 2a and the third layer of resin film 2b are placed on the middle layer 2, and the inner surface of 2a is partially equipped with a special high temperature resistant anti-sticking printing barrier device d, It has high requirements on the raw material performance index of the self-adhesive film itself, and the inner surface of 2a needs to undergo a series of treatments such as corona during printing, and has very special professional requirements for the printing medium, which must be able to achieve heat sealing. A false heat seal is formed between 2a and 2b so that 2a and 2b are not bonded together. After overlapping, heat seal 2 and 1 through the heat seal of the first heat seal a1 and the second heat seal a2, and form a channel a at the same time, and then go through the third heat seal b, the fourth heat seal c1, the second heat seal The heat seal of the fifth heat seal c2 and the sixth heat seal c6 forms a sealed space B that can store medium air. A plurality of spaces B are connected and inflated to form a three-dimensional air packaging material D. The formation of b1 is shown in Figure 3. The heat seal of c2 is due to the barrier characteristics of the special high temperature resistant anti-stick printing barrier device, so that a false heat seal is formed between 2a and 2b. In fact, the first heat seal of c2 is the second layer The resin film 2a is heat-sealed with the first layer of resin film 1, the third layer of resin film 2b and the fourth layer of resin film 3, so that air can easily enter B from between 2a and 2b, thereby filling the entire space of B .

After the air enters the space B, due to the mutual adsorption characteristics between 2a and 2b, when the inflation is stopped, the channel between 2a and 2b is automatically closed, so the air cannot leak out from the space B; in addition, due to the 2 and 1 They are heat-sealed together, so the side of 2 that is not directly heat-sealed with 1 will be subjected to the air pressure of space B, so that 2a and 2b will fit closer together, making B a completely closed space.

The above is the description of the principle of the present invention. It is different from the traditional method of preventing air leakage in the past. It does not need to add additional external auxiliary devices. The air can be stored in a closed space for a long time. Using this principle, a series of related products and derivative products of three-dimensional packaging materials that reject air from the mucous membrane can be produced.

2. Self-adhesive air rejection three-dimensional packaging material distribution and supply main pipe distribution technology: as shown in Figure 1, the air only needs to enter from the opening of the supply main pipe A, and then pass through the distribution of b1, and then enter the space B smoothly through the channel a. Of course, sometimes according to needs, the fourth heat seal c1 may not be heat sealed, and the air source is directly inflated against b1, and the air can also enter B smoothly.

3. Barrier technology of special high temperature resistant anti-adhesive printing barrier device: as shown in Figure 2 and Figure 3, since the inner surface of the second layer of resin film 2a is partially equipped with a special printing barrier device d, its requirements on the raw material performance index of the self-adhesive film itself It is relatively high, and the inner surface of 2a needs to undergo a series of treatment such as corona during printing. There are also very special professional requirements for the printing medium. It must be able to achieve the two-layer resin film 2a and the three-layer A false heat seal is formed between the resin films 2b so that 2a and 2b are not bonded together. Therefore, due to the barrier characteristics of the special printing barrier device, the heat seal of the fifth heat seal c2 forms a false heat seal between 2a and 2b. In fact, the first heat seal of c2 is to heat seal 2a and 1, 2b and 3 respectively. Together, so that the air can easily enter B from the false heat seal between 2a and 2b, so that the entire B space forms an airtight seal.

Self-adhesive film repelling air U-shaped air packaging bag for three-dimensional packaging materials: as shown in Figure 5, use the seventh heat-sealing c3 and the eighth heat-sealing c4 two heat-sealing knife molds, so that the two heat-sealing c3 and c4 are along the folding surface B2 The middle folds are overlapped, the sixth heat seal c6 and the fifth heat seal c2 are overlapped, and then the two sides of B1 and B3 are folded and heat-sealed along the two sides of B2, and one side is the fourth heat seal c1 and the fifth heat seal One end of the intake air supply distribution manifold A formed between the heat seals c2 is closed, and the other end is used as an inflation opening. After being folded and inflated in this way, a regular U-shaped air packing bag is formed.

This air-packing bag adopts the supply main pipe distribution air intake technology, and uses 2a part to have a special high temperature resistant anti-sticking printing barrier device d, so that b1 formed by the bottom edge part of a1 and the heat sealing of c2 on d is an empty false Heat sealing, so that air can easily enter from the opening of distribution supply manifold A, since the other end of A is closed, so the air can only enter from b1, and enter each space B through distribution channel a. The three-dimensional air-packing material U is formed after multiple connected Bs are simply heat-sealed, folded and inflated. When the inflation is stopped, the gap between 2a and 2b is automatically adsorbed together due to the special properties of the inner surface of the film itself. In addition, the effect of air pressure makes the adhesion between 2a and 2b closer, so that Make it impossible for the incoming air to leak out from each B. An air-packing bag with multi-faceted protection properties can be formed.

Since each B is an independent space, when one of them is damaged, the other air chambers B will not be affected. In practical application, this packaging bag can be used to package items individually, or multiple items can be used to package items. For example, in order to reduce the packaging cost, without reducing the protective performance of the article, two U-shaped packaging bags can be used to pack the article, which can also play a good protective performance. Moreover, the packaging method of two U-shaped packaging bags in pairs also solves the disadvantage that a single U-shaped packaging bag cannot provide all-round protection. Therefore, this kind of packaging bag is a popular product packaging, and it is very easy to use.

What needs to be emphasized is that the U-shaped bag, O-shaped bag, and C-shaped bag mentioned above are not the entire content of the present invention, but just different types of packaging bags we manufacture; and the folding surface is not only a single Plane, in practical application, the folding surface can be made into an inverted V shape by heat sealing and folding, so that the U-shaped packaging bag forms a W-shaped packaging bag, and the O-shaped packaging bag forms a II-shaped packaging bag; after such deformation, The packaging bag can withstand greater load impact, and the cushioning performance can be greatly improved. For some items with special requirements, we usually use the above methods to provide packaging to provide safer protection for the items.

In a word, any change in the shape of the product by changing the shape of the heat seal, the way of folding, the size and position of the heat seal, or through different cutting, as long as the purpose of the present invention can be achieved, belongs to the scope of the present invention.
