Problems solved by technology

[0007] The air packaging devices disclosed above are all sealed air chambers composed of two layers of film. When packaging some packages that need to be protected from light or anti-static, you must first coat the package with a layer of light-proof or anti-static packaging bags, and then Putting it into the air packaging device, such two processes not only waste the time of packaging, but also increase the cost of packaging

Embodiment Construction

[0032] The three-layer air-packing device of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0033] Primary plastic sealing refers to the process of sealing two layers of thermoplastic film and one-way valve to form a flat bag that can store air. Secondary plastic sealing refers to folding the semi-finished product after primary plastic sealing and sealing it again along the secondary plastic sealing line. The process of forming a three-dimensional bag that can hold objects.

[0034] Such as Figure 1-3 Shown, is an embodiment of the present invention, figure 1 It is a schematic diagram of the three-layer air packaging device of the present invention before secondary plastic sealing; figure 2 yes figure 1 The air packaging device shown is a schematic diagram of the upper and lower ends after being folded left and right in half; image 3 yes figure 1 Longitudinal sectional view at middle F. The three-laye...

Abstract

The invention discloses a three-layer air packing device. Two rectangular thermoplastic films are subjected to secondary hot laminating to form a three-dimensional packaging body which is provided with an opening and can seal air; the three-dimensional packaging body comprises a plurality of independent sealed air chambers and a main channel; the main channel is provided with an air inlet; each sealed air chamber is communicated with the main channel through a one-way valve consisting of a one-way valve film; the inner side of the three-dimensional packaging body is provided with an inner bag; and the inner bag is formed by fixing four sides of a rectangular lightproof and / or antistatic thermoplastic film on the four sides of the rectangular thermoplastic film on the inner side of the outside three-dimensional packaging body. By the packing device, the consumption of lightproof or antistatic bags for packaging objects to be packaged is reduced, a procedure of sleeving the lightproof or antistatic bag is eliminated, the packaging time is greatly shortened, and possible accidents in the packaging process are further reduced, so that the cost is saved.

Description

technical field [0001] The invention relates to a three-dimensional air-tight packaging device designed and produced using self-adhesive film rejection (one-way valve) technology. The device can be used in precious and fragile products such as electronic products, glassware, precision instruments, handicrafts, printing consumables, etc., and has safety protection performance. Various fields with relatively high requirements. Background technique [0002] The globalization trend of enterprises has increased the transportation distance of products from the place of production to the place of consumption, resulting in the rapid development of the demand for protective packaging during transportation. Traditional expanded polystyrene (EPS) and polyethylene foam (EPE) products must be foamed or processed by the manufacturer before they can be transported to users. The bulky foam after molding is very inconvenient for transportation and storage. Foam-in-place materials developed...
