TPU multi-layer coextruded composite materials are a type of material that achieves a composite of 3-5 different materials through a multi-component step coextrusion process. They feature aesthetically pleasing surfaces and can be made with various textures. They offer excellent strength, wear resistance, and safety and environmental protection properties. They are used in high-strength special composite products such as inflatable life jackets, dive BC jackets, liferafts, inflatable boats, inflatable tents, inflatable water bags, massage air bags, medical protection, industrial conveyer belts, and professional waterproof backpacks.

This production line utilizes multiple extruders and several unwinding units, with stepwise casting and online one-step lamination capabilities. It is equipped with in-line multi-group thickness control and designed for various composite methods. A single line can produce multiple product forms. For specialized fabrics, it can be synchronized and connected with a pre-treatment and coating production line, catering to customers' diverse product manufacturing needs.
