Thermoplastic PolyUrethane(TPU) Films
We Takeda Sangyo are one of the few Thermoplastic PolyUrethane (TPU) film maker in Japan.
Our Tough Grace grade TPU has high elastic like a rubber and tear-resistant.
For example, it is used as a buffer material for PC transportation. The PC is sandwiched between two thin TPU films look like wrap film and hang in a cardboard box. Our TPU film fits tightly and keep it safe during the transportation. Manufacturing thin and transparent TPU film requires highly advanced technology. We Takeda Sangyo are one of the few Thermoplastic PolyUrethane (TPU) film maker in Japan.4 attractive things our Tough Grace grade TPU has
It is manufactured with polyethylene separator by our own method of manufacturing. Easy to process heat-sealing! Available for -30℃ to 60℃ in wide temperature range because it is strongly-designed. In addition, it has an air-barrier which means that it has variety of uses.

1High impact and friction resistance

2Over 500% elasticity

3High transparency available for display and interior design

4High water-vapor permeation, which means that outstanding moisture permeability
Composition a cross section of film

Characteristics and Uses
1High impact and friction resistance
2Over 500% elasticity


3Elastic recovery like a rubber
― suitable for base material of types and band
Recovery Rate
Each samples were stretched by 50%, 100%, 200%, 300% for each 15 mm wideness films, and the elongation to length before loading was measured when the load was freed after 5 minutes. The smaller the value, the better the recovery elasticity.

④Puncture strength that can withstand even a pointed object such as a ballpoint pen.

⑤High water-vapor permeation, which means that outstanding moisture permeability

⑥Air-barrier suitable for balloons and air buffer material

⑦transparency available for display and interior design
⑧Followingness fitting a bent face
⑨Available for -30℃ to 60℃ in wide temperature range
⑩Available for high frequency welding process As a substitute for PVC film
