Description

Inflatable packaging device and manufacturing method thereof

technical field

The invention relates to the packaging field, in particular to an air-filled packaging device and a manufacturing method thereof.

Background technique

With the changes in modern lifestyles and the rapid development of the logistics industry, many items are traded in the form of logistics, such as electronic products, chemical products, pharmaceutical products, ceramics, glass and other daily necessities, etc., where these items are stored or transported During the process, it is inevitable that extrusion, collision, drop, etc. will occur, resulting in product damage or deformation, and causing serious losses to people.

In order to protect the product, before storage or transportation, people will use packing boxes to pack the product, and the purpose of protection is achieved by providing the product with a certain buffering effect. Currently commonly used packaging boxes include paper packaging boxes and inflatable packaging bags. Traditional paper packaging boxes cannot provide a good cushioning effect and cannot provide good protection. Therefore, in the process of use, it is often necessary to use foam, Flexible plastics, etc. put the products to be packaged through multi-layer packaging, and then put them into the packaging box to achieve good anti-drop and anti-collision performance, but this will undoubtedly increase the transportation cost, and the packaging is extremely inconvenient, which not only wastes time, but also reduces work efficiency. , and increased labor costs, which no longer meet the needs of the modern transportation industry.

Currently on the market, some larger-sized packaging items such as computers and servers are still packaged in a combination of foam materials and packaging cartons. The use of foam material together with the packaging box can indeed achieve a good packaging effect and protect the packaged items. But the foam itself is structurally fragile. When the foam material is directly impacted or rubbed, it is easily broken. In addition, the foam material is likely to cause debris pollution, which not only brings unpleasant feelings to users, but also easily causes environmental pollution.

Inflatable packaging materials achieve the cushioning effect by filling the film interlayer with gas, which can be inflated at the packaging site and put into use, so compared with traditional packaging materials, it has the advantages of low transportation cost, easy storage, and better cushioning performance , but also conducive to environmental protection. However, the structure of the inflatable packaging materials currently on the market still cannot meet the market demand. The applicant of the present invention conducts research on air-filled packaging materials and develops different air-filled packaging devices suitable for different packaging items.
