Problems solved by technology

However, on the one hand, the air cushion of this structure also has the problems of low inflation efficiency due to the small size of the air neck, and the inflation saturation and compression resistance need to be improved.
On the other hand, due to the simple columnar structure of the airbag, the wrapping property of the package and the performance of folding and curling are relatively poor.
In addition, most of the existing public products are made of polyolefin, nylon and other materials, which will generate a lot of waste after use, causing pollution to the environment
[0004] In summary, although some products for cushioning packaging are disclosed in the prior art, trying to solve the problems in the field of cushioning packaging, however, due to the design differences in the structure of products such as air cushions, the inflation saturation of these cushions, Compressive performance, etc. need to be further optimized and improved

preparation example Construction

[0042] The second aspect of the present application provides the preparation method of the fully degradable kraft paper cushion air cushion as described above, which includes the following steps:

[0043] (1) The POE material containing 30% 1500 mesh calcium carbonate is used to flush the screw;

[0044] (2) Place the kraft paper roll on the machine frame, pull it to the casting die of the laminating machine through the traction wheel, and heat the traction roller, casting die and screw;

[0045] (3) Add the raw materials for the preparation of the inner layer into the coating machine, and coat the surface of the kraft paper on the frame of the machine, then press the cooling roller, cut and roll to obtain the air cushion film;

[0046] (4) Place two layers of the air-cushion film on the unwinding rack in such a way that the coated surfaces of the air-cushion film face each other, and heat the mold of the machine, and then heat-seal the interlayer air-cushion film.

Abstract

The invention relates to the technical field of buffer packaging, in particular to a completely degradable kraft paper buffer air cushion and a preparation method thereof. The completely degradable kraft paper buffer air cushion comprises a plurality of air storage units formed by heat sealing of two layers of air cushion films and an air supply channel, wherein an inflation inlet is formed in the air supply channel; heat sealing rings are arranged at the tops of the air storage units, an air inlet is formed between every two adjacent heat sealing rings, and the air supply channel is connected with the air storage units through the air inlets; each air storage unit is composed of a plurality of air storage chambers, and the plurality of air storage chambers are connected through air necks; and the air storage chambers are provided with S-shaped structures. Needle-type calcium carbonate is added into a degradable lamination material of the buffer air cushion as a modifier, so that the crystallization property and the melt strength of the material after lamination are improved, the lamination opening is improved, and the tensile strength is improved; and in addition, the buffer air cushion is provided with a special structure, and by adjusting and controlling the shape structure of the air storage chambers, the size of the air necks and the like, the inflation saturation of a product is improved, and the wrapping buffering effect of the air cushion is improved.

Description

technical field [0001] The invention relates to the technical field of cushioning packaging, in particular to a completely degradable kraft paper cushioning air cushion and a preparation method thereof. Background technique [0002] With the change of modern life style and the rapid development of the logistics industry, many items are traded in the form of logistics. During the storage or transportation of these items, it is inevitable that extrusion, collision, drop, etc. will occur, resulting in product damage or deformation. , 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 ...
