[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] A durable packaging bag, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the packaging bag includes a packaging bag body 1, a storage cavity 2 inside the packaging bag body 1, an easy-tear sealing opening 3 for opening the storage cavity 2, a horizontal plate 4 on one side of the storage cavity 2 near the easy-tear sealing opening 3, a fixing plate 5 on the other side of the storage cavity 2 near the easy-tear sealing opening 3, a guide end 51 for controlling the position of the horizontal plate 4 on one end of the fixing plate 5 near the horizontal plate 4, and a fixing component rotatably mounted on the fixing plate 5 for engaging with the horizontal plate 4 to close the storage cavity 2.

[0018] Practical effect: The easy-tear sealing opening 3 makes it easy to open the packaging bag initially, and through the cooperation of the horizontal plate 4, the fixing plate 5 and the fixing components, the storage cavity 2 can be re-formed into a closed space to prevent the items in the storage cavity 2 from being affected by the external environment.

[0019] like Figure 1 , Figure 2 as well as Figure 3 As shown, the fixing component includes a pressing end 7 and a fixing end 6 fixedly connected to the pressing end 7. The pressing end 7 is rotatably disposed on the outside of the packaging bag body 1 along the direction of the fixing plate 5, and the fixing end 6 is rotatably disposed in the storage cavity 2 and fits against the end face of the horizontal plate 4 near the storage cavity 2. An elastic element is provided between the fixing plate 5 and the fixing end 6 to maintain the snap-fit ​​state. Specifically, the pressing end 7 is provided with anti-slip texture to increase the friction between the user's hand and the pressing end 7, making it convenient for the user to perform the pressing operation.

[0020] like Figure 1 , Figure 2 as well as Figure 3 As shown, the elastic element is a torsion spring 9. One end of the torsion spring 9 abuts against the side of the fixing plate 5 away from the storage cavity 2, and the other end of the torsion spring 9 abuts against the side of the fixing end 6 close to the storage cavity 2. The torsion spring 9 is designed so that the fixing end 6 always remains engaged with the horizontal plate 4 without the action of external force.

[0021] like Figure 1 , Figure 2 as well as Figure 3 As shown, in order to enhance the locking stability between the fixed end 6 and the horizontal plate 4 and prevent unlocking without external force, ratchet mechanisms 8 with opposite directions are specially provided on the end faces of the fixed end 6 and the horizontal plate 4 that are in contact with each other. These ratchet mechanisms 8 interlock with each other, effectively preventing the fixed end 6 and the horizontal plate 4 from separating unintentionally.

[0022] Usage process: First, the user tears open the easy-tear sealing opening 3, and then presses the pressing end 7 with one hand, so that the fixed end 6 moves away from the horizontal plate 4 as the pressing end 7 is pressed, thereby releasing the jamming state between the pressing end 7 and the horizontal plate 4, opening the storage cavity 2. After the user has taken out the items, by pressing the horizontal plate 4, the storage cavity 2 returns to the closed state under the action of the torsion spring 9 and the ratchet mechanism 8.

[0023] like Figure 1 As shown, the upper end of the fixing plate 5 is provided with an extension 10, and the extension 10 is provided with a through hole 11 for easy hanging. The design of the extension 10 and the through hole 11 not only facilitates the hanging operation of the packaging bag when storing or displaying it, but also makes the packaging bag easy to hang on the shelf in retail environments such as supermarkets, so that customers can easily view and purchase it.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
