Congratulations on the successful authorization of our company's new utility patent for a 7-layer co extrusion blown film equipment for producing high barrier films!
On June 24, 2025, Hubei Jinzhongde Science and Technology Machinery Equipment Co., Ltd. declared a new practical patent of "a kind of 7-layer co extrusion film blowing equipment for producing high barrier films", which was officially authorized by the China National Intellectual Property Administration. This is another important achievement made by the company in the field of multi-layer co extrusion blown film equipment technology.
This patent is aimed at the high requirements of packaging materials for "barrier performance" and "composite structure" in the fields of food, medicine, chemical engineering, etc. It has made technological breakthroughs in key aspects such as co extrusion accuracy control, layer stability, cooling and shaping, and traction coordination in multi-layer blown film technology, and successfully developed a 7-layer co extrusion equipment suitable for the production of high barrier functional films.
By optimizing the die structure, accurately controlling the flow rate of each layer of raw materials, and temperature control system, this equipment not only greatly improves the quality of interlayer adhesion of thin films, but also enhances the overall thickness uniformity, production efficiency, and automation level. It can be widely used in high-end packaging films, new energy films, and other fine fields.
The approval of this patent not only reflects the research and development depth of Jinzhongde Technology in high-end blown film equipment, but also injects strong momentum into the company's continuous promotion of domestic equipment technology upgrading. In the future, the company will continue to adhere to the path of technological innovation and create more valuable equipment solutions for customers.
