Abstract

The invention relates to a return plug type air packaging device. Two thermoplastic film layers are subjected to thermal plastic packaging twice to form a three-dimensional packaging body which is provided with an opening and can seal the air, the three-dimensional packaging body comprises a plurality of independent sealing air chambers and a main channel, the main channel is provided with an air inlet, each sealing air chamber is communicated with the main channel by virtue of a check valve composed of a check valve film, the three-dimensional packaging body is also internally provided with an inner bag which can not be aerated, and the inner bag is formed by plastically packaging an outward extending section at one side of an opening of the packaging body and the other side of the opening or the outward extending section at the other side and is suspended in the inflated three-dimensional packaging body. The invention provides an air packaging device applicable to packaging of materials which are about to be packaged and provided with edges on the surface. By applying the packaging device, the packaging film for the materials to be packaged is saved; and meanwhile, a packaging film packaging process is eliminated, the packaging time is greatly reduced, and the accident probably existing in the packing process is further reduced, thus the cost is saved.

Description

technical field

[0001] The method 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, and printing consumables, as well as 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 f...
