In 2025, Changzhou Hefeng Packaging Materials Co., Ltd. applied for a patent for an edge correction device for ultra-high molecular weight polyethylene (UHMWPE) carbon fiber composite film. This device aims to optimize edge control in the film production process, improve film width stability, and increase the yield of finished products.
The application of this technology helps to improve the production accuracy of ultra-high performance composite materials and promote the industrial development of high-strength functional film materials.
