TPU film in eyes of TPU tape manufacturer

Both TPU tape and TPU film are made from TPU raw material by physical process. But the specific methods are different. TPU tape is made by extrusion technology, including process drying, dosing, melting, extruding and cooling. However, TPU film is made by calender, film blowing, coating, etc..

Because of the excellent performance of TPU, TPU film and TPU tape are widely used in various fields. Moreover, TPU products are even replacing PVC products in more and more fields. Generally, TPU elastic tape is a kind of garment accessory that sewed at the shoulder part of T-shirt for shaping. It is also used for swimwear, shoe-band, kneecap, wash towel, mask ear-loops and many other textile products. But TPU film has much larger surface area than TPU tape and less elasticity. TPU tape is just a thin tape while TPU film is just like a large piece of fabric. So TPU film is widely used as water resisting material. Manufacturers combine TPU film and textile fabric by radio-frequency to make it waterproof. Besides, TPU film is also used as stealth car cover to protect car paint or add unique pattern on cars.

Besides manufacturing technology and usage, the most obvious difference between TPU tape and TPU film is the appearance. As what we say before, one is a piece of tape and another one is a large piece of film. However, there still some customers send pictures of TPU film to TPU tape manufacturers. Actually, if TPU film is cut into narrow tape in wheel package, it is not easy for some customers to distinguish. But even being cut into a piece of tape, TPU film has different surface with TPU tape. Because of the different manufacturing technology, TPU tape inevitably owns some non-obvious water-wave pattern. But TPU film is smooth and no lines on surface.
