[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, an anti-permeation environmentally friendly paper bag provided by an embodiment of the present invention includes a paper bag main body 1, which is composed of a wear-resistant layer 9, a base material layer 8, a buffer layer 7, a tensile layer 6 and an anti-permeation layer 5. The wear-resistant layer 9 is arranged on one side of the base material layer 8, the buffer layer 7 is arranged on one side of the base material layer 8, the tensile layer 6 is arranged on one side of the buffer layer 7, and the anti-permeation layer 5 is arranged on one side of the tensile layer 6. The wear-resistant layer 9 is the outer wall layer, and the buffer layer 7, the tensile layer 6 and the anti-permeation layer 5 are all inner wall layers. Paper bag handles 4 are provided on both sides of the paper bag main body 1, and the two paper bag handles 4 correspond to each other. A sealing cover 2 is provided on one side of the paper bag main body 1, and a buckle assembly 3 is provided between the sealing cover 2 and the other side of the paper bag main body 1.

[0024] Specifically, in this embodiment, the base material layer 8 is made of a biodegradable fiber material, such as a corn starch-based composite material, polylactic acid or pulp; the anti-permeation layer 5 is made of environmentally friendly materials such as wax, bioplastics or diatomaceous earth, which can effectively prevent the penetration of moisture and grease; the tensile layer 6 is made of a biaxially oriented polypropylene film, a polypropylene film or a nylon film, which can effectively improve the load-bearing capacity of the paper bag during use and increase the structural strength of the paper bag; the buffer layer 7 is an air bubble film made of polypropylene film, which can provide buffering capacity for the items in the bag; the wear-resistant layer 9 is a wear-resistant coating, which can increase the durability of the paper bag body 1 during use; the sealing cover 2 is made of the same soft material as the paper bag body 1, and one end of the sealing cover 2 is fixed to the paper bag body 1 by glue; by pulling one end of the sealing cover 2, the sealing cover 2 can seal the opening on the upper side of the paper bag body 1; and then the one end of the sealing cover 2 is fixed by the snap assembly 3, so that the sealing cover 2 maintains a sealed state on the opening on the upper side of the paper bag body 1.

[0025] The utility model provides an anti-permeation environmentally friendly paper bag, wherein the snap assembly 3 includes a fixed shell 10, a card plate 12, a fixed block 13, and an inserting plate 14. A slot 15 is provided on one side of the fixed shell 10, and the inserting plate 14 is fixedly mounted on one side of the fixed block 13 and movably inserted into the slot 15. A card block 18 is provided at one end of the inserting plate 14. A sliding cavity 11 is provided in the fixed shell 10, and the card plate 12 is slidably mounted in the sliding cavity 11, and the card plate 12 and the card block 18 are engaged. A spring 17 is provided between the card plate 12 and the inner wall of the sliding cavity 11. The fixed shell 10 is fixedly mounted on one side of the paper bag body 1, the fixed block 13 is fixedly mounted on one side of the sealing cover 2, and a pressing block 16 is provided at one end of the card plate 12, and the pressing block 16 is located on one side of the fixed shell 10.

[0026] In another embodiment provided by the present invention, when the sealing cover 2 needs to be fixed, the sealing cover 2 is rotated and folded so that the sealing cover 2 seals the opening on the upper side of the paper bag body 1. At the same time, the inserting plate 14 and the card block 18 are inserted into the slot 15. Then, when the chamfered surface of one end of the card block 18 contacts the chamfered surface of one end of the card plate 12, the card block 18 squeezes the card plate 12. The card plate 12 is squeezed and moves into the sliding cavity 11, and squeezes the spring 17, causing the spring 17 to deform. Then, when the card block 18 is misaligned with the card plate 12, the inserting plate 14 and the card plate 12 are misaligned. When the locking cam 12 is aligned, the elastic force of the spring 17 can drive the card plate 12 to move upward, so that the card plate 12 contacts the inserting plate 14, and the card plate 12 can engage the card block 18, thereby fixing the sealing cover 2. The card plate 12 and the sliding cavity 11 are both U-shaped. When the sealing cover 2 is limited, the pressing block 16 is pressed so that the pressing block 16 drives the card plate 12 to retract into the sliding cavity 11, thereby releasing the engagement with the card block 18, and then pulling the fixing block 13 so that the fixing block 13 drives the inserting plate 14 and the card block 18 to move out of the slot 15, thereby completing the limiting of the sealing cover 2.

[0027] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
