They are only for the convenience of describing the present invention 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 invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figures 1-5 An embodiment of this utility model is provided: a high-temperature resistant eight-side seal packaging bag, including a packaging bag body 1, a polytetrafluoroethylene coating 13 sprayed on the outer walls of the packaging bag body 1, a ceramic coating 14 sprayed on the outer walls of the polytetrafluoroethylene coating 13, a first storage groove 2 fixedly provided on both sides of the packaging bag body 1, a partition plate 5 fixedly provided at the center of the interior of the packaging bag body 1, and a second storage groove 6 provided on both sides of the partition plate 5.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, in use, the PTFE coating 13 provides an extremely low coefficient of friction and excellent self-lubricating properties. It not only exhibits excellent high-temperature resistance but also extremely high chemical stability, reacting almost entirely with no chemicals and demonstrating strong corrosion resistance. Furthermore, the ceramic coating 14 provides excellent high-temperature resistance, able to withstand high temperatures without deformation or damage. It also possesses superior corrosion resistance, resisting the erosion of various chemicals. Through the synergistic effect of the PTFE coating 13 and the ceramic coating 14, not only can… Improving the heat resistance and corrosion resistance of the packaging bag also enhances its protection, preventing the bag's appearance from being compromised by high temperatures. Furthermore, the inclusion of the first storage slot 2, the divider 5, and the second storage slot 6 facilitates the categorization and placement of stored items, making it more convenient for users. This addresses the problem of the eight-side-seal packaging bag in the previous design lacking heat resistance, which, in practical use, easily turns black in certain areas due to high temperatures, thus reducing its aesthetic appeal.

[0029] Fixing blocks 10 are provided on both sides of the top of the packaging bag body 1 above the first storage slot 2. Each of the two adjacent fixing blocks 10 is provided with an installation slot 11 on the side away from each other. An installation block 12 is movably arranged inside the installation slot 11. A screw hole 8 is provided on the lower surface of the installation block 12. A screw rod 9 is provided inside the screw hole 8. A connecting plate 7 is fixedly connected to the side away from each other of the two installation blocks 12. A lifting rope 4 is fixedly connected to the side of the connecting plate 7 away from the installation block 12. A soft rubber sleeve 3 is fitted on the outer wall of the lifting rope 4.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during use, the soft rubber sleeve 3 and the lifting rope 4 facilitate the lifting and carrying of the packaging bag. When the lifting rope 4 breaks, the screw 9 can be rotated until it disengages from the screw hole 8. Then, the connecting plate 7 can be moved along the outside until the mounting block 12 disengages from the mounting groove 11, thus completing the disassembly of the lifting rope 4. Similarly, the lifting rope 4 can be installed. By facilitating the disassembly and replacement of the lifting rope 4, the packaging bag can be reused, thereby improving the practicality of the device.

[0031] Working Principle: In this application, firstly, the polytetrafluoroethylene (PTFE) coating 13 is applied. PTFE coating 13 has an extremely low coefficient of friction and excellent self-lubricating properties. It not only exhibits excellent high-temperature resistance but also extremely high chemical stability, reacting almost entirely with no chemical substances and possessing extremely strong corrosion resistance. Furthermore, the ceramic coating 14 is applied. Ceramic coating 14 has good high-temperature resistance, able to withstand high temperatures without deformation or damage. It also has excellent corrosion resistance, resisting the erosion of various chemical substances. Through the synergistic effect of PTFE coating 13 and ceramic coating 14, not only is the heat resistance of the packaging bag improved, but its corrosion resistance is also enhanced, thus providing excellent protection for the packaging bag. To avoid reducing the aesthetic appeal of the packaging bag due to high temperatures, the first storage slot 2, the divider 5, and the second storage slot 6 facilitate the categorization and placement of stored items, making them easier for users to use. Finally, the soft rubber sleeve 3 and the lifting rope 4 make it easy to lift and carry the packaging bag. When the lifting rope 4 breaks, the screw 9 can be rotated until it disengages from the screw hole 8. Then, the connecting plate 7 can be moved outward until the mounting block 12 disengages from the mounting slot 11, thus completing the disassembly of the lifting rope 4. Similarly, the lifting rope 4 can be installed. By facilitating the disassembly and replacement of the lifting rope 4, the packaging bag can be reused, thereby improving the practicality of the device.
