[0023] 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.

[0024] See also Figure 1-4 , the utility model provides a technical solution;

[0025] A biodegradable and environmentally friendly plastic bag includes a plastic packaging shell 1. The outer side of the plastic packaging shell 1 is fixedly connected to a side drawstring 2, the top of the side drawstring 2 is fixedly connected to a top support drawstring 4, the bottom of the plastic packaging shell 1 is provided with a protection component, the inner side of the plastic packaging shell 1 is provided with a classification component, and the top of the plastic packaging shell 1 is provided with a convenient drawstring component. The entire plastic bag is produced using PLA material.

[0026] Furthermore, the classification component includes a side draw rope 2 and a classification partition 6. The inner side of the plastic packaging shell 1 is fixedly connected to an internal classification layer 5, and the inner side of the internal classification layer 5 is fixedly connected to a classification partition 6. Through the action of the classification partition 6, the biodegradable and environmentally friendly plastic bag can be used to classify and bag items according to needs during use.

[0027] Furthermore, when the classification component is not opened, a shrinkage fixing component is arranged between the classification component and the plastic packaging shell 1, and the shrinkage fixing component includes a connecting adhesive strip 12 and a shrinkage internal classification layer 13. The inner side of the plastic packaging shell 1 is fixedly connected with the shrinkage internal classification layer 13, and the top surface of the shrinkage internal classification layer 13 is fixedly connected with the connecting adhesive strip 12. The inner top surface of the plastic packaging shell 1 is fixedly connected with the connecting adhesive strip 12. The shrinkage internal classification layer 13 is fixedly connected to the plastic packaging shell 1 by the connecting adhesive strip 12. At the same time, when the biodegradable and environmentally friendly plastic bag does not need to be classified during use, the shrinkage internal classification layer 13 is shrunk by the connecting adhesive strip 12 so that the internal space can be fully utilized, thereby avoiding space waste.

[0028] Furthermore, the top surface of the plastic packaging shell 1 is fixedly connected to a connecting layer 9 , the top surface of the connecting layer 9 is fixedly connected to a top tie-opening layer 7 , and a convenient tie-opening component is provided on the inner side of the top tie-opening layer 7 .

[0029] Furthermore, the convenient drawstring assembly includes a top drawstring layer 7 and a drawstring bag 8. A protective cavity 14 is provided on the inner side of the top drawstring layer 7, and a stretch drawstring groove 10 is provided in the middle of the top surface of the top drawstring layer 7. The inner side of the protective cavity 14 is fixedly connected to the drawstring bag 8. Through the mutual cooperation of the drawstring assemblies, the plastic mouth needs to be drawstringed when extracting small items in large quantities. Through the action of the drawstring assembly, the drawstringing becomes more convenient and quick.

[0030] Furthermore, the protective component includes a bottom leak-proof layer 3 and a bottom tensile protection rope 11. The bottom of the plastic packaging shell 1 is fixedly connected with the bottom tensile protection rope 11, the inner side of the side pull rope 2 is fixedly connected with the bottom tensile protection rope 11, and the bottom surface of the side pull rope 2 and the bottom tensile protection rope 11 is fixedly connected with the bottom leak-proof layer 3. Through the action of the bottom tensile protection rope 11, when the biodegradable and environmentally friendly plastic bag is used to extract items, the bottom tensile protection rope 11 shares the pressure for the bottom to avoid the bottom from breaking due to heavy objects. At the same time, through the action of the bottom leak-proof layer 3, while avoiding the bottom from breaking, the overall bearing capacity of the biodegradable and environmentally friendly plastic bag for extracting heavy objects is also improved.

[0031] Working principle: When the present invention is needed and the internal parts need to be classified and placed, the connecting adhesive strip 12 is torn off from the inner side of the plastic packaging shell 1, thereby opening and shrinking the internal classification layer 13 so that the internal classification layer 5 and the classification partition 6 are directly matched in shape for classification and placement. When a drawstring is needed, the drawstring bag 8 on the inner side of the drawstring groove 10 is stretched and the drawstring bag 8 is pulled so that the top drawstring layer 7 as a whole shrinks toward the center, thereby completing a convenient and fast drawstring. At the same time, the bottom leak-proof layer 3 and the bottom stretch protection rope 11 cooperate to make the bottom of the plastic bag more stable, preventing the bottom from being broken and damaged when heavy objects are extracted.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
