[0025] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0026] Refer to Figures 1-5 As shown in the figure, a plastic packaging bag that can be folded and expanded in multiple segments includes a packaging bag body 1. A sealing disc 11 is provided at the top of the packaging bag body 1. First magnetic strips 12 and second magnetic strips 13 are provided on both sides inside the sealing disc 11. The packaging bag body 1 includes an upper packaging bag 2 and a lower packaging bag 3. A rotating rod 22 is provided on one side inside the upper packaging bag 2. One side of a partition cloth 23 is arranged on the outer surface of the rotating rod 22. Cable ties 24 are arranged on the outer surface of the partition cloth 23 and inside the upper packaging bag 2. The two groups of cable ties 24 are engaged through a zip fastener head 25. A clamping member 26 is fixedly mounted at the bottom end of the partition cloth 23. A clamping block 32 is fixedly mounted at the top end inside the lower packaging bag 3. First creases 21 and second creases 31 are arranged on the left and right side surfaces of the upper packaging bag 2 and the lower packaging bag 3. Two handle strips 14 are fixedly mounted at the top of the packaging bag body 1. Waterproof layers are arranged inside the upper packaging bag 2 and the lower packaging bag 3. There are four groups of both the clamping member 26 and the clamping block 32, and the positions of the clamping member 26 and the clamping block 32 correspond to each other.

[0027] In this solution, the packaging bag is composed of the upper packaging bag 2 and the lower packaging bag 3. Users can, according to their needs, fold and store the lower packaging bag 3 when using the upper packaging bag 2, or use both in combination to meet storage requirements of different capacities. The first magnetic strip 12 and the second magnetic strip 13 provided inside the sealing disc 11 adopt a magnetic attraction design to ensure that the packaging bag can fit tightly when closed, effectively preventing the leakage of contents, and at the same time facilitating quick opening and closing, thus enhancing the user experience. Through the combination of the partition cloth 23 on the rotating rod 22, the cable 24 and the zipper head 25, users can easily adjust the internal space partition of the packaging bag to adapt to the storage needs of items, improving the space utilization rate. When the lower packaging bag 3 needs to be stored, users only need to simply align the card part 26 with the card block 32 and snap it in to achieve a firm connection between the two. This snap connection method is not only easy to operate but also firmly connected, ensuring the stability and safety of the packaging bag when loading items. Waterproof layers are provided inside both the upper packaging bag 2 and the lower packaging bag 3 to effectively protect the contents from moisture erosion, making it suitable for carrying in various humid environments or liquid items. The two handle strips 14 provided at the top of the packaging bag body 1 facilitate users to carry it by hand, enhancing the portability of the packaging bag. Through the design of the first crease 21 and the second crease 31, users can easily fold the packaging bag into a smaller volume for easy storage, and when needed, quickly unfold it to the required size to meet the usage requirements of different scenarios.

[0028] The working principle of the present utility model: The sealing of the packaging bag body 1 is achieved through the sealing disc 11 at the top. The first magnetic strip 12 and the second magnetic strip 13 inside the sealing disc 11 attract each other to tightly close the packaging bag opening, ensuring the safety of the contents. The packaging bag body 1 is composed of a foldable upper packaging bag 2 and a lower packaging bag 3. A rotating rod 22 is provided inside the upper packaging bag 2, and a partition cloth 23 is arranged on it. By operating the zipper head 25, users can easily untie or close the two cables 24, thereby opening or closing the partition cloth 23. The flexible opening or closing of the partition cloth 23 allows users to divide the internal space of the packaging bag into different-sized parts according to storage needs. In addition, the first crease 21 and the second crease 31 are provided on both sides of the upper packaging bag 2 and the lower packaging bag 3, facilitating users to fold the packaging bag into a smaller volume when not in use, saving storage space. At the same time, the waterproof layer provided inside the packaging bag effectively prevents moisture penetration and protects the safety of the stored items. When only the upper packaging belt is used after the partition cloth 23 is closed, the card part 26 at its bottom will be folded with the lower packaging bag 3 through the second crease 31 and snapped with the card block 32 inside its top end, enhancing the structural stability of the packaging bag and also improving the user experience. Finally, two handle strips 14 are equipped at the top of the packaging bag body 1, facilitating users to carry it by hand or hang it, increasing the convenience of use.

[0029] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, various changes and improvements will occur to the present utility model, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
