Multi-functional composite coating production line: all materials are compatible, and the intelligent manufacturing has unlimited possibilities
This production line innovatively integrates multi-resin extrusion and high-speed casting technology, supports LDPE/PP/EVA/TPU/TPE and other resins, and is compatible with the precision lamination of 20 substrates such as BOPP, BOPET, aluminized film, and paper. Through a single extrusion casting, micron-level uniform coating is achieved, which significantly improves the barrier, strength and aesthetics of the material. Specially designed for high value-added products such as digital photo paper, paper containers, food-grade lunch boxes/paper cups, medical cardboard, etc., it empowers the upgrading of the global packaging and printing industry with the advantages of intelligent control, flexible production replacement and energy saving.
