[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 and 2As shown, a biodegradable plastic express packaging bag includes a bag body 1 and a cap 2. The cap 2 is integrally connected to the opening of the bag body 1. A first sealing structure 3 and a second sealing structure 4 are provided on one side of the cap 2. An opening structure 5 is provided on one side of the bag body 1. The opening structure 5 is located between the first sealing structure 3 and the second sealing structure 4. A waterproof strip 6 is provided on the other side of the bag body 1. The waterproof strip 6 is correspondingly provided with the opening structure 5.

[0021] According to the above structure, in use, one side of the cap 2 is first fixedly adhered to one side of the bag body 1 through the first sealing structure 3, thereby sealing the bag body 1. When opening, the cap 2 is torn open through the opening structure 5, so that the cap 2 between the first sealing structure 3 and the second sealing structure 4 is disconnected, thereby opening the cap 2. After opening, the cap 2 can be glued to one side of the bag body 1 again through the second sealing structure 4, and the bag body 1 is sealed again, which facilitates the reuse of this packaging tape.

[0022] like Figure 2-4 As shown, both the first sealing structure 3 and the second sealing structure 4 include a double-sided adhesive strip 31, which is fixedly pasted on one side of the cover 2, and a plastic strip 32 is pasted on one side of the double-sided adhesive strip 31.

[0023] According to the above structure, when sealing the bag body 1, first tear off the plastic strip 32 to expose one side of the double-sided adhesive strip 31, and then use the double-sided adhesive strip 31 to stick one side of the cap 2 to one side of the bag body 1 to close the opening of the bag body 1.

[0024] like Figure 2 As shown, the opening structure 5 includes two easy-tear leads 51 disposed on the surface of the cover 2. A plastic reinforcing strip 52 is fixedly bonded to one side of the cover 2. The plastic reinforcing strip 52 is disposed between the two easy-tear leads 51, and one end of the plastic reinforcing strip 52 protrudes from one end of the cover 2.

[0025] According to the above structure, when opening the bag, the cap 2 is broken along the two easy-tear leads 51 by pulling the plastic reinforcing band 52, thereby allowing the bag body 1 to be opened.

[0026] like Figure 2-4 As shown, a biodegradable plastic protective film 11 is provided on the outer wall of the bag body 1 and one side of the cap 2. The materials of the bag body 1 and the cap 2 are both paper. A pressure groove 12 is provided on one side of the cap 2. The pressure groove 12 is corresponding to the opening structure 5.

One end of the waterproof tape 6 protrudes from one end of the cap 2.

[0027] According to the above structure, when tearing open the sealing structure 5, the waterproof tape 6 is first torn off. When tearing the plastic reinforcing tape 52, the biodegradable plastic protective film 11 on the outside will crack from the groove 12. During transportation, the waterproof tape 6 is attached to the inside of the groove 12, which can cover the groove 12 and thus improve the waterproof performance of the outside of the packaging bag.

[0028] The working principle of this utility model is as follows: In use, the first sealing structure 3 first fixes one side of the cap 2 to one side of the bag body 1, thereby sealing the bag body 1. When opening, the opening structure 5 tears open the cap 2, breaking the cap 2 between the first sealing structure 3 and the second sealing structure 4, thus opening the cap 2. After opening, the second sealing structure 4 can be used to re-attach the cap 2 to one side of the bag body 1, sealing the bag body 1 again. This facilitates the reuse of the packaging tape. When sealing the bag body 1, the plastic tape 32 is first torn off to expose both sides. One side of the adhesive strip 31 is exposed, and then one side of the cap 2 is pasted to one side of the bag body 1 by the double-sided adhesive strip 31 to close the opening of the bag body 1. When opening, the cap 2 is broken along the two easy-tear leads 51 by pulling the plastic reinforcing strip 52, so that the bag body 1 can be opened. When tearing the opening structure 5, the waterproof strip 6 is torn off first. When the plastic reinforcing strip 52 is torn off, the biodegradable plastic protective film 11 on the outside will crack from the groove 12. During transportation, the waterproof strip 6 is pasted inside the groove 12 to cover the groove 12, thereby improving the waterproof performance of the outside of the packaging bag.

[0029] The above description is merely a preferred embodiment of this utility model.
