What is TPU Film?
TPU Film (full name: thermoplastic polyurethane film) is a high-performance film material made primarily from thermoplastic polyurethane (TPU). It combines the high elasticity of rubber with the processability of thermoplastic plastics, exhibiting excellent elasticity, transparency, oil resistance, grease resistance, and abrasion resistance. Depending on the application requirements, TPU film can be prepared using molding processes such as casting, extrusion, or blow molding, and is widely used in footwear, clothing, electronic products, automotive interiors, and medical devices.

Main Manufacturing Processes
- Casting: TPU raw material is heated and melted through an extruder, then uniformly cast onto cooling rollers to form a film. This process produces films with uniform thickness, high transparency, and a smooth surface, suitable for applications requiring high transparency or high precision.
- Blown Film: Molten TPU material is blown into a film using airflow, then cooled, shaped, and wound up. This process is suitable for producing films with high flexibility, thinness, and excellent toughness, commonly used in clothing, packaging, and protective applications.
- Calendering: Molten TPU resin is repeatedly calendered using a multi-roll calendering machine to produce TPU films with greater thickness and stable mechanical properties. This process is commonly used in applications requiring high strength, such as automotive interiors, industrial protective materials, and shoe composites.
