TPU multi-layer coextrusion composite material is a material that achieves the bonding of 3-5 layers of different materials through a multi-component step coextrusion process, featuring aesthetically pleasing surface shaping and the ability to create various patterns. It boasts superior strength, wear resistance, and safety with environmental protection properties. It is used in high-strength, specialized composite products such as dive BC jackets, life rafts, inflatable boats, inflatable tents, inflatable water bladders, inflatable self-inflating mats, massage air bags, industrial conveyor belts, and professional waterproof backpacks.

This production line utilizes multiple extruders and unwinding units, achieving step-by-step cast film forming and online一步composite forming. It is equipped with in-line multi-group thickness control. The production line is designed with various composite methods, enabling the production of multiple product forms on a single line. For special fabrics, it can be synchronized and connected with a pre-treatment and coating production line, meeting the production needs of different customer products.
