[0021] REFERENCE Figures 1-4 A packaging bag easy to tear and pull, comprising a bag body 1 and a nylon pull rope 2, the packaging bag 1 is provided with a kraft paper outer layer 101, a polypropylene inner layer 102 and a moisture-proof layer 103 from outside to inside, wherein the polypropylene inner layer 102 and the moisture-proof layer 103 are provided with the nylon pull rope 2.

[0022] In other embodiments, the moisture-proof layer 103 is made of any one of polyethylene, polypropylene, aluminum foil or PET, and the thickness of the moisture-proof layer 103 is 0.2-0.8mm;

[0023] Through the design, by setting the moisture-proof film 103, the moisture from the outside can be prevented from entering the inside of the bag body 1, thereby protecting the articles in the bag body 1 from the moisture;

[0024] One end of the nylon pull rope 2 extends out of the bag body 1;

[0025] In other embodiments, the end of the nylon pull rope 2 extending out of the bag body 1 penetrates the polypropylene inner layer 102 and the kraft paper outer layer 101 in sequence, and the end of the nylon pull rope 2 extending out of the bag body 1 is at least 1cm;

[0026] Through the design, the nylon pull rope 2 has the characteristics of high strength and light weight, thereby being easy to be pulled and opened subsequently;

[0027] In the embodiment, by setting the nylon pull rope in the bag body, when the user needs to open the packaging bag, the user only needs to pull the pull rope to make the pull rope tear the kraft paper outer layer and the polypropylene inner layer of the bag body in sequence, and the nylon pull rope also tears the moisture-proof film coated on the innermost side of the bag body at the same time, thereby achieving the purpose of tearing the packaging bag neatly and improving the experience of the user.

[0028] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
