Description

Functional self-adhesive one-way air blocking three-dimensional packaging material and preparation method thereof

The invention relates to a packaging material and a preparation method thereof, in particular to a functional self-adhesive unidirectional air resistance which can be applied to precious fragile products such as electronic products, glassware, precision instruments and meters, handicrafts, and products with high safety protection performance. Broken three-dimensional packaging material and its preparation method. Background technique

Packaging is the means to realize the value of goods and the value of use, and is the bridge between the production and consumption of goods. Green packaging is the packaging that requires packaging materials to save resources, reduce waste, be easy to recycle or reuse, or easily decompose naturally, not pollute the environment, and protect consumers' health. The packaging industry has also become one of the largest polluting and wasteful industries in the rapid development. The many drawbacks of expanded polystyrene (EPS) products have become increasingly serious and have become a "white pollution". Relative to the buffer products used only for short-term transportation, the disposal of permanent polystyrene foam packaging can cause serious pollution to the environment. Combustion produces toxic gases; and the accumulation of geological structures is caused by the inability to corrode. Therefore, in combination with various industries, buffer protection, demand analysis of filled products and "4R1D" principles are reduced, reusable and recyclable, using air (the cheapest, environmentally friendly packaging medium) as buffer protection. We have designed a self-adhesive one-way air blocking technology through the use of minimal packaging materials, ie environmental resources, and through the plastic recycling system that has been implemented in many countries, using air and film to form a functional packaging material. . The biggest difficulty of this invention is how to quickly and easily inflate and how to ensure the use of air and product functions throughout the circulation of goods. Traditional original practices, such as balloons, are inflated and tied with a string to prevent air leakage. There are also a series of complicated valves or plugs, such as stop valves, safety valves, mechanical valves, on-off valves, etc. There are certain one-sidedness and inconvenience in actual production and use operations.

With the development of the market economy and the improvement of people's multi-level consumer demand, the function of modern packaging should not only be limited to the protection of goods, but also need to facilitate storage and transportation, facilitate the use, beautify goods, convey information, promote sales, shape product image, and enhance Brand image, environmental protection, etc. However, the current packaging materials have a single function and cannot meet the packaging requirements of some high-end products.

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 4, the first aspect of the present invention: Air enters through the opening of the distribution supply pipe A, passes through the gap between 2a and 2b through the false heat seal bl and passes through the distribution passage a, from 2a and 2b The gap between the gaps smoothly enters each space B. As the air flow increases, the space B begins to expand gradually. When the inflation is stopped, the gap between 2a and 2b is automatically adsorbed due to the special properties of the inner surface of the film itself. Together, with the effect of air pressure, the adhesion between 2a and 2b is tighter, so that the incoming air can not leak out from B, and the invention realizes the one-way leakage prevention function of film self-adhesive adsorption. .

As shown in Fig. 5 to Fig. 7, the second content of the present invention: cl and c2 form an air distribution supply manifold A, and the top ends of cl and c2 are in contact with b, which are closed together, and air enters from the opening, from the false heat The seal bl flows into each space B through the passage a, so that when the air source is directly connected to the opening of the supply main pipe A (which may be the product side end or the top of the product), the air will pass through the split of bl and a. It automatically enters each air chamber B, which makes it very convenient and quick to use the product, greatly improving work efficiency.

The third aspect of the invention: implementation of a false heat seal bl. The heat seal of c2 acts directly on d, 1 (functional plastic film) and 2a are heat-sealed by the action of c2, while 3 (functional plastic film) and 2b are heat-sealed by the action of c2, where 2a is the inner surface Partially equipped with a special high temperature resistant anti-adhesive composite barrier device d, which requires high requirements on the raw material properties of the self-adhesive film itself, and requires a series of physical treatments on the inner surface of the 2a composite layer during the compounding process, and the composite medium is also very Special professional requirements must be able to bond 2a and 2b together during heat sealing. The separation between 2a and 2b is due to the special composite barrier, so that the false heat seal bl is achieved and the air can easily enter the space 8.

As shown in FIG. 10, the fourth, fifth and sixth contents of the present invention can be heat-sealed by a special process of a plastic film of a special function. The three-dimensional air-packing material as described is composed of 1 (puncture-resistant, wear-resistant functional plastic film) as a surface material, 3 (black-proof plastic film) as an inner layer material, and 2a, 2b, two relatives, 1 and 3 A narrow, specially treated plastic film is placed in the intermediate layer. After overlapping according to the product packaging design requirements, after 5, 6 heat sealing, a gas can be introduced into the branch 4 of the A, which can be For single or several. The overlapped multi-layer plastic film is heat-sealed through 8, 9, 10 to form a manifold passage A for gas to enter, and the gas only needs to enter from the opening of the manifold A (if the opening is the side end, the other end is thermally closed) If the opening is at the top, the ends of the manifold are thermally closed), and the bottom of the 5, 6 and 10 contacts form 7, see Figure 9; 7 using the spacer sealing technique to make the 10 form a virtual Heat sealed. Thus, the air enters from the header A and enters the space A through the branch 4 to become a reality. The spacer sealing technique is for preventing the heat seal from forming the manifold passage B, and the means for preventing the 2a and 2b from being heat-sealed by the air entering the branch pipe 4. Referring to Fig. 8, the pad C is placed in the position space of 7, and D1 and D2 are simultaneously operated up and down. The overlapped four-layer plastic film is further heat-sealed by 11, 12, 13, 14, 15, 16, 17, 18 to form a space B in which a contiguous gas medium can be stored. The characteristic of B is that each connected B space has its own function. If one of the breakages leaks, the other Bs are not affected. At the same time, the B feature is used for one-time inflation. After the inflation is completed, the air leakage is prevented by the self-adhesive one-way barrier technology. The plurality of associated B spaces form a self-adhesive unidirectional air blocking three-dimensional packaging material, which can be formed into a bag shape by a product shape design such as a folded heat seal, as shown in FIG. The pouch packaging material has become a new packaging material that combines different functions. The sealed bag is provided with a sealing line 19, which is processed to seal the user after being placed in the packaged product without affecting the supply manifold and the branch pipe 4, and thus does not affect the function of the inflation after sealing. When the product is placed in a sealed, inflated package, the packaging is completed. This sealed bag is shock-resistant, anti-drop, anti-wear, waterproof, and protected from light.
