[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 In this embodiment: a puncture-proof and tensile-resistant composite plastic packaging bag includes a packaging bag body 1, an opening is provided at the top of the packaging bag body 1, a first connecting plate 3 and a second connecting plate 4 are fixedly installed on both sides of the opening, and a protective layer 9 is provided on the inner and outer sides of the packaging bag body 1.

[0023] In this embodiment, the packaging bag body 1 includes two groups of plastic base layers 6. The corresponding sides of the two groups of plastic base layers 6 are respectively fixedly provided with an anti-stab layer 7 and a tensile layer 8, and the anti-stab layer 7 and the tensile layer 8 are fixedly connected together.

[0024] In this embodiment, a handle opening 5 is provided at the center of the first connecting plate 3 and the second connecting plate 4. A buckle 301 is fixedly installed on the side of the first connecting plate 3 close to the second connecting plate 4, and a slot 401 adapted to the buckle 301 is provided on the side of the second connecting plate 4 close to the first connecting plate 3, and the buckle 301 and the slot 401 are both located on both sides of the handle opening 5. By setting the buckle 301 and the slot 401, the opening can be closed to prevent items inside the packaging bag body 1 from falling, and at the same time, the packaging bag body 1 can be easily carried by hand through the handle opening 5.

[0025] In this embodiment, the tensile layer 8 is composed of a square metal object 801 on the outside and metal wires 802 crisscrossed in the middle of the square metal object 801 to form a mesh. When subjected to external force, the crisscrossed metal wires 802 can increase the tensile resistance of the packaging bag body 1, making it less likely to deform.

[0026] In this embodiment, the stab-proof layer 7 is composed of a nylon layer 701 and a Kevlar layer 702 fixed together. By using the nylon layer 701 and the Kevlar layer 702 together, the double-layer protective structure can improve the puncture-proof ability of the packaging bag body 1, reduce the probability of the packaging bag body 1 being punctured, and make the packaging bag body 1 not easily damaged during use.

[0027] In this embodiment, the protective layer 9 is made of a waterproof and oil-proof material. By providing the protective layer 9, the waterproof and oil-proof properties of the packaging bag body 1 are improved, and water vapor and grease can be prevented from invading the interior of the packaging bag body 1 to a certain extent.

[0028] In this embodiment, both ends and the bottom of the packaging bag body 1 are provided with folds 101 . The provision of the folds 101 makes it more convenient for the user to store the packaging bag body 1 .

[0029] The working principle and usage process of the present invention are as follows: when in use, the first connecting plate 3 and the second connecting plate 4 are pulled to both sides respectively to open their openings, and then the items to be packaged are placed inside the packaging bag body 1. After the packaging is completed, the buckle 301 and the card slot 401 are matched to close the opening and the packaging bag body 1 is conveniently carried by hand through the handle 5. When the packaging bag body is hit by sharp objects, the nylon layer 701 and the Kevlar layer 702 are matched, and the double-layer protection structure can improve the puncture resistance of the packaging bag body 1, reduce the probability of the packaging bag body 1 being punctured, and make the packaging bag body 1 not easy to be damaged during use. When it is pulled by external force, the metal wires 802 arranged in a criss-cross pattern can increase the tensile strength of the packaging bag body 1, making it not easy to deform.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
