Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic bags, especially to an environment-friendly double-layer plastic bag. BACKGROUND

[0002] Plastic bags are bags made of plastic as the main raw material, and the commonly used plastics include polypropylene, polyester and nylon, etc. They are essential items in people's daily life and are often used to pack other items. They are widely used due to their low cost, extremely light weight, large capacity and convenience for storage. However, they are prohibited from production and use in some countries due to their long degradation period and difficulty in disposal.

[0003] The commonly used food plastic bags are mostly made of polyethylene film, which is non-toxic and can be used to pack food. Another kind of film is made of polyvinyl chloride, which is also non-toxic by itself. However, the additives added according to the use of the film are often harmful substances to the human body and have certain toxicity. Therefore, this kind of film and the plastic bags made of the film are not suitable for packing food.

[0004] The opening of the traditional plastic bag is usually simply folded or tied with a rope, which has poor sealing performance. In addition, the opening of the traditional plastic bag is not firm, and the items are easy to fall off during carrying or moving. Especially for valuable or fragile items such as electronic products and glass products, once they fall off, it may cause loss. When carrying liquid or easily leaking items, leakage is easy to occur, which pollutes other items or the environment. Due to the lack of effective sealing mechanism, air and moisture are easy to enter the bag, which causes the items in the bag to be damp, oxidized or deteriorated, especially for items such as food and medicine which have high requirements for the environment. SUMMARY

[0005] The utility model aims at solving the problem of the existing technology that the plastic bag is not convenient to seal, and provides an environment-friendly double-layer plastic bag.

[0006] In order to solve the problem of the existing technology, the utility model adopts the following technical scheme:

[0007] An environment-friendly double-layer plastic bag, comprising an outer plastic bag body, a protective layer and a sealing assembly.

[0008] The inner layer plastic bag body is arranged inside the outer plastic bag body.

[0009] The protective layer is arranged on the outer plastic bag body.

[0010] The sealing assembly is arranged on the inner walls of the two sides of the inner layer plastic bag body, and the sealing assembly comprises a first connecting mechanism and a second connecting mechanism for sealing the plastic bag.

[0011] Further, a plastic bag handle is arranged on the outer plastic bag body.

[0012] Further, the protective layer is composed of a plastic layer and a sponge layer.

[0013] Further, a waterproof layer and a leakage-proof layer are sequentially arranged between the plastic layer and the sponge layer from left to right.

[0014] Further, the first connecting mechanism comprises a first connecting piece and a plug-in piece; the first connecting piece is arranged on the inner wall of one side of the inner plastic bag body; and the plug-in piece is arranged on the first connecting piece.

[0015] Further, the second connecting mechanism comprises a second connecting piece and a fixing piece; the second connecting piece is arranged on the inner wall of the other side of the inner plastic bag body, the plug-in piece is inserted into the second connecting piece; the fixing piece is embedded with the plug-in piece through the top of the second connecting piece; and a moving piece is arranged on the fixing piece to facilitate the removal of the fixing piece.

[0016] Further, a strip-shaped slot is arranged on the plug-in piece for the insertion of the fixing piece.

[0017] Compared with the prior art, the utility model has the beneficial effects that:

[0018] In the utility model, the sealing assembly is arranged to provide reliable sealing protection, firmly seal the plastic bag, prevent the articles in the bag from falling during carrying or moving, and is particularly important for some valuable or fragile articles, such as electronic products, glass products and the like; for liquid or easily-leaked articles, the sealing assembly provides reliable sealing protection to prevent the articles from leaking during carrying or storage, and is particularly important when the double-layer plastic bag is used, because the double-layer structure itself has enhanced the leakage-proof performance, and the sealing assembly further ensures the sealing property.
