Description

Technical Field

[0001] The utility model relates to the technical field of paper bags, in particular to a high-strength paper bag. Background Art

[0002] A paper bag is a bag made of paper as the main material. Paper bags usually have the following characteristics: environmental protection, light weight, strong printability, and paper bags are widely used. For example, paper bags are used to store things in supermarkets, gift bags used to wrap gifts to increase the beauty of gifts, and file bags used to store documents and materials.

[0003] Prior art includes a utility model with publication number CN216735499U, which discloses a high-strength portable paper bag. The patent adopts a bag body and a handle. Through grooves are provided on both sides of the top of the bag body. An elastic member is provided at the top of the through groove. The bottom of the through groove is slidably connected to a mounting seat through a sliding member. When the mounting seat is connected to the through groove, the top of the mounting seat fits the elastic member. A plurality of through holes for the handle to pass through are provided on the surface of the mounting seat. The two ends of the handle are connected to each other through a connecting member. The utility model reduces the acting force between the mounting seat and the bag body through the cooperation between the through groove, the elastic member, the sliding member, the mounting seat, the through hole and the connecting member, thereby improving the service life of the bag body, and solving the problem that most of the paper bags on the market are provided with handles at the top for the convenience of people to lift, and generally the handles are directly glued to the paper bag. When people use the handles to lift the paper bag, the acting force between the handle and the paper bag will be concentrated at the connection between the two. After long-term use, the place is easily damaged.

[0004] The inventor has found in his daily work that in the process of using paper bags to hold things, there are existing paper bags such as the above-mentioned ones that only reinforce the handles and the sticking parts of the paper bags to improve the strength of the paper bags. However, since the weight of the paper bags is mostly accumulated at the bottom of the paper bags when the things are held, the load on the bottom of the paper bags is relatively high. Since the bottom structure of the paper bags is relatively weak, when the paper bags are held, the bottom of the paper bags is often damaged, causing the things held to spill. Utility Model Content
