[0002] Plastic packaging bags are made of plastic as raw material. They are widely used in the production and life of various supplies because of their low price, extremely light weight, large capacity and easy storage. They are widely used in daily life and industrial production.

[0003] At present, some extra-thick plastic bags are generally composed of a transparent bag body and a tubular handle. The tubular handle is hot-melt fixed to the bag body during production. When the bag body contains too heavy items or has been used for a long time, the hot-melt portion between the tubular handle and the bag body may fall off directly, and the bag does not have a good tensile effect, resulting in a low use effect. Therefore, it is urgent to design a tensile-resistant plastic bag to solve the above problem. Utility Model Content
