Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inflatable packaging bags, in particular to a self-closing inflatable packaging bag with an inner lining film. Background Art
[0002] The space filling of traditional packaging boxes is generally made of foam, which is placed in the box according to the shape of the items. Especially when fragile items are placed in the box, the foam cushion fills the remaining space of the packaging box. The volume of such space filling is larger than the volume of the protected items, and the post-use treatment of the foam cushion also brings inconvenience to environmental protection. In particular, the transportation and storage of foam are very troublesome, which greatly increases the transportation and storage costs of enterprises. Therefore, most of them use self-closing inflatable packaging bags to wrap and protect items. Self-closing inflatable packaging bags are a new type of packaging material. It uses the inflation principle to provide better protection and support when packaging items. The principle of inflatable packaging bags is to use the pressure of gas to provide support and protection, thereby protecting the packaged items from damage. The following problems exist in the prior art:
[0003] Because the existing self-closing inflatable packaging bags are made of a single-layer, one-piece polyethylene material, when wrapping and protecting items with sharp corners, the inflation cavity may be squeezed and leak, thereby reducing the cushioning protection effect. At the same time, the existing self-closing inflatable packaging bags need to wrap the items when in use. If the items are large, they can only be wrapped in multiple self-closing inflatable packaging bags and then fixed with transparent tape, resulting in the problem that the self-closing inflatable packaging bags are more troublesome to use when wrapping items, and it is also inconvenient to take out the items. Utility Model Content
[0004] The utility model provides a self-closing inflatable packaging bag with an inner lining film to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A self-closing inflatable packaging bag with an inner lining film comprises an inflatable film sheet, wherein the inflatable film sheet comprises a self-closing inflatable cavity, an inner lining film is fixedly installed on the inner wall of the self-closing inflatable cavity, built-in inflatable balls are arranged on the upper and lower sides of the inner cavity of the self-closing inflatable cavity, and an inflatable ball reinforcement film is fixedly installed on the inner wall of the built-in inflatable ball.
[0007] A further improvement of the technical solution of the utility model is that a Velcro fleece surface is fixedly installed on the outer wall of the left front end of the inflatable diaphragm.
[0008] A further improvement of the technical solution of the utility model is that a second Velcro surface is fixedly installed on the front outer wall of the right end of the inflatable diaphragm.
[0009] A further improvement of the technical solution of the utility model is that a Velcro hook surface 1 is fixedly installed on the outer wall of the rear side of the left end of the inflatable diaphragm.
[0010] A further improvement of the technical solution of the utility model is that a second Velcro hook surface is fixedly installed on the outer wall of the rear side of the right end of the inflatable diaphragm.
[0011] By adopting the above technical scheme, through the mutual cooperation between the Velcro fleece surface 1, the Velcro fleece surface 2, the Velcro hook surface 1 and the Velcro hook surface 2 in the scheme, the overall self-closing inflatable packaging bag can be combined by sticking the Velcro fleece surface 1 to the Velcro hook surface 2 of another self-closing inflatable packaging bag when wrapping larger items, so that they can be freely spliced and combined.
[0012] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0013] 1. The utility model provides a self-closing inflatable packaging bag with an inner lining film, which adopts an inflatable membrane, a self-closing inflatable cavity, and an inner lining film. By arranging the inner lining film on the inner wall of the self-closing inflatable cavity evenly arranged on the outer wall of the inflatable membrane, the outer wall strength of the self-closing inflatable cavity is higher, and the pressure resistance is further improved. The problem that the existing self-closing inflatable packaging bag is made of a single-layer one-piece polyethylene material, which leads to the problem that when wrapping and protecting objects with sharp corners, the inflatable cavity is likely to rupture and leak due to squeezing, thereby reducing the buffering protection effect, the self-closing inflatable packaging bag can be adapted to sharp objects of different degrees, thereby ensuring the performance stability of the self-closing inflatable packaging bag during transportation.
[0014] 2. The utility model provides a self-closing inflatable packaging bag with an inner lining film, which adopts the cooperation of Velcro fur surface one, Velcro fur surface two, Velcro hook surface one, and Velcro hook surface two. The Velcro fur surface one of one inflatable membrane piece is pasted with the Velcro hook surface two of another inflatable membrane piece, and the inflatable membrane pieces can be continued to be pasted and spliced according to the size of the article, and then the Velcro fur surface two of the last inflatable membrane piece is pasted with the Velcro hook surface one to wrap the article. This solves the problem that the existing self-closing inflatable packaging bag needs to wrap the article when in use. When the article is large, it can only be wrapped with multiple self-closing inflatable packaging bags and then wrapped and fixed with transparent tape, which results in the problem that the self-closing inflatable packaging bag is more troublesome to use when wrapping the article and it is also inconvenient to take out the article. The utility model achieves the effect that the self-closing inflatable packaging bag can be freely combined without the need to wrap with transparent tape, so it is easy to wrap and disassemble.

[0020] The present invention is further described in detail below in conjunction with the embodiments:
[0021] Example 1
[0022] like Figure 1-4 As shown, the utility model provides a self-closing inflatable packaging bag with an inner lining film, including an inflatable film sheet 1, the inflatable film sheet 1 includes a self-closing inflatable cavity 2, and an inner lining film 21 is fixedly installed on the inner wall of the self-closing inflatable cavity 2.
[0023] In this embodiment, an inner lining membrane 21 is arranged on the inner wall of the self-closing inflation cavity 2 which is evenly arranged on the inner wall of the inflatable diaphragm 1. The inner lining membrane 21 is made of polyvinylidene fluoride membrane material. As the pore size of the membrane continues to decrease, the membrane binds to low molecular weight proteins more firmly, becomes translucent, and has a certain flame retardant effect to prevent combustion, thereby making the outer wall strength of the self-closing inflation cavity 2 higher.
[0024] Example 2
[0025] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, built-in inflatable balls 22 are provided on both upper and lower sides of the inner cavity of the self-closing inflatable cavity 2, and an inflatable ball reinforcement membrane 221 is fixedly installed on the inner wall of the built-in inflatable ball 22.
[0026] In this embodiment, two built-in inflatable balls 22 are simultaneously provided in the inner cavity of the self-closing inflatable cavity 2, and are closely attached to the inner wall of the self-closing inflatable cavity 2, thereby further improving the pressure and scratch resistance of the self-closing inflatable cavity 2. The inflatable ball reinforcement film 221 on the inner wall of the built-in inflatable ball 22 is made of TPU hot melt adhesive film material, which is a high-strength, high-transparency, wear-resistant, high-temperature resistant, and chemically resistant hot melt adhesive film. It is made of polyurethane material and has excellent physical and chemical properties. It can effectively protect and ensure the strength of the built-in inflatable ball 22, so that after the self-closing inflatable cavity 2 leaks, the built-in inflatable ball 22 can still provide shock-absorbing protection for objects.
[0027] Example 3

[0029] In this embodiment, the Velcro fleece surface 11 of one of the inflatable membrane sheets 1 is glued to the Velcro hook surface 2 14 of another inflatable membrane sheet 1, and the inflatable membrane sheets 1 can be continued to be glued together according to the size of the object. Then, the Velcro fleece surface 2 12 of the last inflatable membrane sheet 1 is glued to the Velcro hook surface 1 13 to wrap the protected object. The Velcro can be torn off for disassembly.
[0030] The working principle of the self-closing inflatable packaging bag with liner film is described in detail below.
[0031] like Figure 1-4 As shown, by arranging an inner lining film 21 on the inner wall of the self-closing inflatable cavity 2 evenly arranged on the inner wall of the inflatable diaphragm 1, the outer wall strength of the self-closing inflatable cavity 2 is made higher, and at the same time, two built-in inflatable balls 22 are arranged in the inner cavity of the self-closing inflatable cavity 2, and are tightly attached to the inner wall of the self-closing inflatable cavity 2, so that the pressure and scratch resistance of the self-closing inflatable cavity 2 is further improved, and by pasting the Velcro fur surface 11 of one of the inflatable diaphragms 1 with the Velcro hook surface 2 14 of another inflatable diaphragm 1, the inflatable diaphragms 1 can be continued to be pasted and spliced according to the size of the object, and then the Velcro fur surface 2 12 of the last inflatable diaphragm 1 is pasted with the Velcro hook surface 1 13 to wrap the protected object.
[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
