What is the concept behind two-layer TPU and PET composite films, and what are their advantages?

Two-layer TPU and PET composite films are made by laminating a PET film onto a TPU film using roller pressing and winding techniques. This combination leverages the advantages of both TPU and PET materials.

Advantages of TPU and PET composite films include:

1. Elasticity: The two-layer structure provides excellent flexibility, allowing the film to maintain shape during printing and processing without distortion or contamination.
2. Processing convenience: The composite film is easy to handle and can be readily used in printing, coating, and laminating processes.
3. High-end applications: Widely used in advanced electronics and optical fields, offering good optical performance and protection for delicate surfaces.

In addition to two-layer TPU-PET films, we also produce three-layer PET-TPU-PET composite films to meet specific application requirements, providing enhanced mechanical strength, protection, and stability.

Overall, TPU-PET composite films combine the softness and elasticity of TPU with the strength, stability, and optical clarity of PET, making them ideal for demanding industrial and electronic applications.
