A sealing piece 10 is fixedly connected to the bottom of the convenient opening 12. The rear side of the sealing piece 10 is fixedly connected to a reverse Velcro 11. The rear side of the reverse Velcro 11 is adhesively connected to the front side of the positive Velcro 9. The inner wall of the bag body 1 is provided with a heat-insulating and puncture-resistant structure 2. The heat-insulating and puncture-resistant structure 2 is used for puncture resistance and high temperature resistance. Handle straps 13 are fixedly connected to the front and back sides of the top of the bag body 1, and a thickened protective pad 14 is fixedly connected to the middle part of the handle strap 13.
[0033] Specifically, the bottom of the convenient opening 12 is fixedly connected to a sealing sheet 10, which can effectively prevent air and moisture from entering the bag. The back side of the sealing sheet 10 is fixedly connected to an anti-Velcro 11, and the back side of the anti-Velcro 11 is adhered to the front side of the positive Velcro 9, thereby ensuring the sealing of the convenient opening 12 when closed.

The design of the handle strap 13 allows users to easily lift the bag, and the middle part of the handle strap 13 is also fixedly connected to a thickened protective pad 14, which further improves the comfort and durability of the handle.
[0034] Please see the attached Figure 1 - Attachment Figure 3 The heat-insulating and stab-resistant structure 2 includes a plastic protective film layer 201. The outer wall of the plastic protective film layer 201 is fixedly connected to the inner wall of the bag body 1. The outer wall of the plastic protective film layer 201 is fixedly connected with a high-density polyethylene layer 202. The outer side of the high-density polyethylene layer 202 is fixedly connected with a polypropylene layer 203. The outer wall of the polypropylene layer 203 is fixedly connected with an ultra-high molecular polyethylene layer 204. The outer side of the ultra-high molecular polyethylene layer 204 is fixedly connected with a high-fiber layer 205. The outer wall of the high-fiber layer 205 is coated with a polyurethane coating 206. The outer wall of the high-fiber layer 205 is fixedly connected with a high-temperature resistant plastic layer 207. The top of the plastic protective film layer 201 is fixedly connected with a positive Velcro 23, and the inner wall of the plastic protective film layer 201 is evenly fixedly connected with a zipper edge 22.

This coating has good waterproof and wear-resistant properties and can effectively prevent the invasion of external moisture and impurities. The outer wall of the high-fiber layer 205 is also fixedly connected to a layer of high-temperature resistant plastic layer 207. This layer of high-temperature resistant plastic layer 207 can withstand use in high-temperature environments, ensuring the stability and reliability of the structure under extreme temperature conditions. A positive Velcro 23 is fixedly connected to the top of the plastic protective film layer 201. This design makes the opening and closing of the structure more convenient and firm. The inner wall of the plastic protective film layer 201 is evenly fixedly connected to the zipper edge 22.
[0036] Please see the attached Figure 1 - Attachment Figure 3A drawstring 15 is fixedly connected to the outer side of the top of the sealing sheet 10, and a non-slip pad 16 is fixedly connected to the outer wall of the drawstring 15. Side pockets 17 are fixedly connected to the left and right sides of the bag body 1, and a lock buckle 18 is fixedly connected to the top of the side pocket 17. Vertical partitions 19 are evenly fixed on the inner side of the bottom of the bag body 1, and the front and rear sides of the vertical partitions 19 are fixedly connected to a zipper edge 21. A horizontal partition 20 is fixedly connected to the front side of the inner wall of the bag body 1, and the front side of the top of the horizontal partition 20 is fixedly connected to an anti-Velcro 24.
[0037] Specifically, the function of the vertical partition 19 is to effectively divide the internal space of the bag body 1 so that users can better organize and manage their belongings. The front and rear sides of the vertical partition 19 are fixedly connected with a zipper edge 21. The design of the zipper edge 21 allows users to easily open or close the partition, further improving the convenience of use.

The drawstring 15 is pulled to make the reverse Velcro 11 fixedly connected to the inner wall of the sealing sheet 10 close to the positive Velcro 9 fixedly connected to the periphery of the convenient opening 12 for sealing, so that the opening on the front side of the plastic bag can be sealed, thereby sealing the entire plastic bag, effectively preventing moisture and dust from entering the bag, and preventing the items inside from leaking or overflowing. The sealed plastic bag takes up little space and is easy to stack. Items will not fall out or be mixed with other items, and different items can be marked and classified for storage.
[0039] When the bag body 1 of the plastic bag is filled with objects with sharp edges, the inner wall of the bag body 1 is fixedly connected with a high-temperature resistant plastic layer 207 to withstand high temperatures. The inner wall of the high-temperature resistant plastic layer 207 is coated with a polyurethane coating 206 to reinforce and protect the high-temperature resistant plastic layer 207. The inner wall of the high-temperature resistant plastic layer 207 is reinforced and connected with a high-fiber layer 205, an ultra-high molecular polyethylene layer 204, a polypropylene layer 203, a high-density polyethylene layer 202 and a plastic protective film layer 201 in sequence. The plastic protective film layer 201 that comes into contact with the articles is made of non-toxic and pollution-free materials. With the reinforcement of multiple composite materials, it has high strength and durability, can effectively prevent sharp objects from penetrating, protect the articles in the bag from damage, reduce the risk of accidental damage to articles during transportation and handling, protect the safety of users and goods, reduce the additional costs caused by damage to articles, and improve transportation and storage efficiency.
