When in a humid environment, it is easy to cause damage to the internal items. Content of the Utility Model
[0005] Aiming at the deficiencies of the prior art, the utility model provides a heat-sealed bag that is anti-fouling and easy to tear, so as to solve the problems put forward in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: a heat-sealed bag that is anti-fouling and easy to tear, including a heat-sealed bag body. An opening is provided above the front end of the heat-sealed bag body. A tear strip is provided inside the opening. A matching groove is provided in the bag body corresponding to the tear strip. A waterproof layer is provided on the outside of the heat-sealed bag body;
[0007] A hard tear piece is fixedly installed at the end of the tear strip. A reserved groove is provided in the heat-sealed bag body corresponding to the hard tear piece. A convex block is fixedly installed on the side of the hard tear piece away from the reserved groove.
[0008] As a preferred technical solution of the utility model, the tear strip is arranged in an inverted T shape, and the top of the tear strip extends to the side of the heat-sealed bag body away from the opening.
[0009] As a preferred technical solution of the utility model, tearing lines are provided between the side edges of the tear strip and the connection parts of the opening respectively. A sealing glue layer is provided between the tear strip and the matching groove.
[0010] As a preferred technical solution of the utility model, the tearing line is arranged in a serrated shape.
[0011] Compared with the prior art, the utility model provides a heat-sealed bag that is anti-fouling and easy to tear, and has the following beneficial effects:
[0012] 1. When the anti-fouling and easily tearable heat-sealed bag needs to be opened, by pushing the convex block, the rigid tearing piece is separated from the reserved groove. Then, by pulling the rigid tearing piece around the fitting groove to drive the tearing strip, the tearing strip is separated from the fitting groove, and the tearing line between the tearing strip and the fitting groove is separated, so that the opening is opened, facilitating the user to take out the items inside the heat-sealed bag body.
[0013] 2. For the anti-fouling and easily tearable heat-sealed bag, by setting the sealing glue layer and the waterproof layer, the sealing glue layer makes the tearing strip have good stability, and the waterproof layer can prevent the outside of the heat-sealed bag body from being polluted and can be wiped at the same time.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4 , in this implementation: An anti-fouling and easily tearable heat-sealed bag includes a heat-sealed bag body 1. An opening 2 is provided above the front end of the heat-sealed bag body 1. A tearing strip 4 is provided inside the opening 2. A fitting groove 3 is provided on the heat-sealed bag body 1 corresponding to the tearing strip 4. A waterproof layer 10 is provided on the outside of the heat-sealed bag body 1;
[0021] The end of the tearing strip 4 is fixedly installed with a rigid tearing piece 6. A reserved groove 7 is provided on the heat-sealed bag body 1 corresponding to the rigid tearing piece 6. A convex block 9 is fixedly installed on the side of the rigid tearing piece 6 away from the reserved groove 7. When the opening 2 needs to be opened, by pushing the convex block 9, it is convenient for the rigid tearing piece 6 to be separated from the reserved groove 7.
