[0030] See also Figure 1-4 , an embodiment provided by the utility model:

[0031] A PE plastic bag that is easy to seal, comprising:

[0032] A plastic bag body 1, wherein a heat-pressed edge seal 2 is disposed at the edge of the plastic bag body 1, and a first side positioning groove 3 and a second side positioning groove 4 are disposed on the outer side of the heat-pressed edge seal 2 near the opening of the plastic bag body 1;

[0033] A plastic bag body 1, a middle positioning groove 5 is provided on the outer surface of the plastic bag body 1 near the opening, and an electrostatic adsorption belt 6 is provided on the inner surface of the plastic bag body 1 near the opening;

[0034] The electrostatic adsorption belt 6, and the first sealing zipper 7 and the second sealing zipper 8 are respectively installed on the inner surface of the plastic bag body 1 on both sides of the electrostatic adsorption belt 6.

[0035] The plastic bag body 1 includes a polyethylene layer 101, an outer wear-resistant protective layer 102, an inner film 103 and an antibacterial coating 104. The outer surface of the polyethylene layer 101 is compositely provided with the outer wear-resistant protective layer 102, the inner side of the polyethylene layer 101 is provided with an inner film 103, and the surface of the inner film 103 is provided with an antibacterial coating 104. The above structural design enables the plastic bag body 1 to have a higher structural strength and an antibacterial protection function.

[0036] The thickness of the outer wear-resistant protective layer 102 is not less than 1 / 3 of the thickness of the polyethylene layer 101 , and the thickness of the wear-resistant protective layer 102 is not less than the thickness of the inner coating 103 . The above structural design can prevent the polyethylene layer 101 from being damaged and extend the service life of the polyethylene layer 101 .

[0037] The antibacterial coating 104 is a silver ion coating, and the thickness of the antibacterial coating 104 is greater than 1 / 3 of the thickness of the inner film 103 . The inner film 103 is an aluminum foil. The above structural design has a certain antibacterial effect and can inhibit the growth of bacteria in the plastic bag body 1 .

[0038] In one of the embodiments, the first side positioning groove 3 and the second side positioning groove 4 are symmetrically distributed on both sides of the plastic bag body 1, and the first side positioning groove 3 and the second side positioning groove 4 are symmetrically distributed on both sides of the middle positioning pressing groove 5. The above structural design facilitates the alignment of the middle positioning pressing groove 5 with the sealing component of the household sealing machine, and when necessary, the plastic bag body 1 can also be torn open from the first side positioning groove 3 and the second side positioning groove 4, so as to facilitate the retrieval of the sealed items.

[0039] In one of the preferred embodiments, the length of the middle positioning groove 5 is greater than half of the outer width of the plastic bag body 1, and the center of the middle positioning groove 5 and the center of the electrostatic adsorption belt 6 are on the same vertical plane. The above structural design ensures that the middle positioning groove 5 can be stably aligned and fitted with the sealing component of the household sealing machine, and the inner electrostatic adsorption belt 6 can fit tightly, which is convenient for the sealing machine to seal.

[0040] In one embodiment, the surface of the electrostatic adsorption belt 6 is set to a mirror surface, and the length of the electrostatic adsorption belt 6 is equal to the inner width of the plastic bag body 1. The above structural design enables the surfaces of the electrostatic adsorption belt 6 on both sides of the inner wall of the plastic bag body 1 to be stably adsorbed and adhered to avoid wrinkles.

[0041] In one of the preferred embodiments, the first sealing zipper 7 and the second sealing zipper 8 are symmetrically distributed about the center of the electrostatic adsorption belt 6. The above structural design can assist the hot-pressing sealing of a household sealing machine to perform double sealing on the plastic bag body 1.

[0042] The working principle of the utility model is as follows: when using the device, after putting the articles into the plastic bag body 1, the positioning groove 5 is kneaded from the outside, so that the electrostatic adsorption belt 6 on the inner surface of the plastic bag body 1 is stably attached, and the first sealing clip chain 7 and the second sealing clip chain 8 are squeezed to connect, so as to perform preliminary sealing;

[0043] Then, the middle positioning groove 5 of the outer wall at the opening of the plastic bag body 1 is aligned with the hot pressing part of the household sealing machine, and the household sealing machine performs hot pressing and sealing on the part of the plastic bag body 1 where the electrostatic adsorption belt 6 is arranged inside, and cooperates with the first sealing clip chain 7 and the second sealing clip chain 8 to achieve double sealing. If there is no household sealing machine, the first sealing clip chain 7 and the second sealing clip chain 8 can also be used in cooperation with the electrostatic adsorption belt 6 to achieve stable sealing;

[0044] When it is necessary to take out the items stored in the plastic bag body 1, if a household sealing machine is used, the plastic bag body 1 is directly torn open from the first side positioning groove 3. If a household sealing machine is not used, the first sealing clip chain 7 and the second sealing clip chain 8 can be separated from the opening in sequence.

[0045] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
