[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: a self-sealing and tear-resistant plastic packaging bag, including a packaging bag body 1, a first sealing strip 3 and a second sealing strip 4 fixedly connected to the two sides of the inner cavity of the packaging bag body 1 respectively, a breathable membrane 6 provided on one end surface of the packaging bag body 1, a frame 5 fixedly connected to the surface of the packaging bag body 1, a sliding piece 7 slidably connected to the surface of the frame 5, handle holes 2 opened on both sides of the packaging bag body 1, a handle frame 8 fixedly connected to the surface of the handle hole 2, and an elastic hook 9 rotatably connected to the surface of one handle frame 8;

[0024] A breathable membrane 6 is provided on the surface of the packaging bag body 1 to allow the stored items to breathe. Through the cooperation of the sliding piece 7 and the frame 5, the amount of breathability can be flexibly adjusted according to the characteristics of the items and environmental factors to meet the breathability needs of different items. A handle hole 2 and a handle frame 8 are provided to facilitate the taking out of the packaging bag body 1. The surface of the handle frame 8 is provided with a storage groove 12 and a rotatable elastic hook 9, which can hang the packaging bag body 1. When not in use, the elastic hook 9 can be hidden and stored, which improves the practicality and convenience of the packaging bag body 1.

[0025] Example 2

[0026] Please see Figures 1 to 4 Based on Embodiment 1, in order to allow the packaging bag body 1 to breathe, the surface of the first sealing strip 3 is provided with sealing protrusions, and the surface of the second sealing strip 4 is provided with sealing grooves. The first sealing strip 3 and the second sealing strip 4 are connected to each other. When sealing is required, the two sides of the packaging bag body 1 are first squeezed towards the middle, so that the sealing protrusions on the surface of the first sealing strip 3 are embedded into the sealing grooves on the surface of the second sealing strip 4, thereby achieving a tight seal of the packaging bag body 1, effectively preventing leakage of the contents of the bag or the entry of external impurities, and achieving a self-sealing effect.

[0027] A round hole 11 is provided on one side of the surface of the packaging bag body 1. The breathable membrane 6 is fixedly connected to the surface of the round hole 11. The surface of the breathable membrane 6 is provided with multiple breathable holes. The breathable holes on the breathable membrane 6 can allow the air inside the packaging bag body 1 to exchange with the outside, and the breathable holes can effectively block dust and impurities from entering the interior of the packaging bag body 1.

[0028] A sealing strip 16 is fixedly connected to one end of the surface of the breathable membrane 6. The sealing strip 16 has a ring structure and is made of silicone. When the sliding piece 7 completely covers the surface of the breathable membrane 6 and does not need to be breathable, the sealing strip 16 is sandwiched between the sliding piece 7 and the breathable membrane 6 to improve its sealing performance.

[0029] A sliding groove 15 is provided on the surface of the edge 5 near the packaging bag body 1. The sliding groove 15 provides a track for the movement of the sliding piece 7, and at the same time limits the movement path and range of the sliding piece 7, so that the sliding piece 7 can accurately cover or expose the breathable membrane 6, thereby adjusting the amount of air permeability. The sliding piece 7 is slidably connected to the surface of the sliding groove 15. One end of the surface of the sliding piece 7 is provided with an anti-slip texture. The anti-slip texture increases the friction between the user's fingers and the sliding piece 7 during operation, making the sliding operation more stable and convenient.

[0030] Example 3

[0031] Please see Figures 1 to 5 Based on Embodiment 2, in order to suspend the packaging bag body 1, a storage groove 12 is provided on the surface of a handle frame 8. The storage groove 12 is in the shape of a "J" and is similar in shape to the elastic hook 9. When the elastic hook 9 is not in use, it can be placed in the storage groove 12, thereby preventing the elastic hook 9 from swinging randomly when the packaging bag body 1 is idle or during transportation.

[0032] A central shaft 13 is fixedly connected to one end of the storage slot 12, and the other end of the central shaft 13 is fixedly connected to the surface of the packaging bag body 1. The central shaft 13 is a rotating support component for the elastic hook 9, which allows the elastic hook 9 to rotate around it, realizing the switching from storage state to use state. The elastic hook 9 is made of plastic and has the ability to undergo slight deformation. A shaft hole 14 is opened on one end of the surface of the elastic hook 9, and the central shaft 13 passes through the shaft hole 14. A protrusion 10 is fixedly connected to the other end of the surface of the elastic hook 9. When the elastic hook 9 is placed in the storage slot 12, the user can apply force to the elastic hook 9 through the protrusion 10, thereby removing the elastic hook 9 from the storage slot 12.

[0033] In actual use, the amount of air permeability can be adjusted according to the area covered by the sliding piece 7 on the breathable membrane 6. Slide the sliding piece 7 away from the end of the breathable membrane 6. When the sliding piece 7 completely covers the breathable membrane 6, the air pores on the breathable membrane 6 are blocked and the amount of air permeability is zero. As the sliding piece 7 gradually slides away from the breathable membrane 6, the air pores are gradually exposed and the amount of air permeability increases. The amount of air permeability can be flexibly adjusted by sliding the sliding piece 7 according to the actual needs of the items in the bag.

[0034] When the user needs to carry the main body of the packaging bag 1, they can grip it by passing their fingers through the edge 5 on the surface of the handle hole 2. When the user needs to hang the main body of the packaging bag 1, they can pinch the protrusion 10 and pull the elastic hook 9. The elastic hook 9 will rotate around the central axis 13 and rotate out of the storage slot 12 after a slight deformation. After rotating out, the elastic hook 9 will recover its elastic deformation. The user can then use the elastic hook 9 to hang the main body of the packaging bag 1 in a suitable position. After use, the elastic hook 9 can be rotated back into the storage slot 12 for storage to prevent the elastic hook 9 from shaking or causing obstruction when not in use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
