On July 13, Huaxin Packaging Company's independent research and development of "a hookable anti-cracking square bottom film-covered plastic woven bag and its production method" was authorized by the State Intellectual Property Office as an invention patent, marking another important breakthrough in the technological upgrading of the enterprise in the field of anti-cracking square bottom film-covered plastic woven bag.
Previously, Huaxin Packaging Company has obtained the utility model patent of "hookable anti-cracking film-covered plastic woven bag" in 2024, which effectively improves the durability of the hooking part by adding a reinforced anti-tearing strip above the bag body. The invention patent realizes system upgrade on the basis, and exerts force in two directions from the structural design and the process method: on the one hand, the tensile strength of the bag bottom and the valve port is strengthened, and on the other hand, at least one circle of self-sealing non-woven fabric is arranged on the inner periphery of the valve port channel, so that the firmness of the packaging bag from the bag mouth, the anti-tear strip to the bag bottom forms a gradually increasing gradient. In practical application, the tension generated by the iron hook is dispersed and buffered layer by layer through the multi-layer structure, which not only ensures the smoothness of operation, but also significantly reduces the risk of bag body rupture and material leakage.
In the future, Huaxin Packaging Company will continue to intensify its research and development efforts, continuously optimize product performance around the actual needs of customers, and meet the increasingly diversified market needs with higher quality and more targeted packaging solutions.
