Description

Technical Field

[0001] The utility model relates to the technical field of container bags, in particular to a loading and unloading type polypropylene container bag. Background Art

[0002] Polypropylene bulk bag is a kind of bulk bag made of polypropylene material, which is usually used for packaging and transporting bulk goods. Polypropylene is a lightweight, durable and moisture-proof plastic material. Therefore, polypropylene bulk bag has the characteristics of lightness, durability, moisture-proof and waterproof. It can protect goods from damage and pollution. It can be widely used in chemical, food, medicine, agriculture and other fields to package various solid, liquid and powdered goods.

[0003] A Chinese patent discloses a convenient loading and unloading polypropylene container bag (authorization announcement number CN212502001U). The patented technology makes the shape of the bag body more stable by setting limit frames inside the first card belts at the top and bottom of the bag body. The upper card block and the lower card block can be quickly separated by pressing the first slide bars on both sides of the upper card block. At the same time, the container bag can be quickly unfolded by pulling the limit frame, which is beneficial to improving the efficiency of loading and unloading materials in the container bag. The feed port can be kept open by setting an expansion frame on the outside of the feed port, which is convenient for quick loading and unloading of the container bag.

[0004] However, there are still some shortcomings in this patent. Although the container bag of this patent can expand the feed port, it can be seen from the drawings of this patent that this patent cannot support the container bag, which easily causes the container bag to wrinkle during use and affects the loading work. Therefore, those skilled in the art provide a loading and unloading polypropylene container bag to solve the problems raised in the above background technology. Utility Model Content
