Problems solved by technology

[0007] The air packaging devices disclosed above are all sealed air chambers composed of two layers of film. If the object to be packaged has edges and corners or angular protrusions, the inner film may be punctured, causing the gas in the sealed air chamber to leak. Thereby increasing the possibility of damage to the packaging inside

Embodiment Construction

[0039] The back-plug air-packing device of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] 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.

[0041] Such as figure 1 As shown, a schematic diagram of an embodiment before secondary plastic sealing, the whole is formed by two rectangular films a and b of the same size after one plastic sealing, and the one-way valve F and the main channel T formed by two layers of small films are arranged in The middle part of the film a, b, wherein the main channel sealing line 1 and the bottom sealing line 2 will be divided into a non-...

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...
