Functional Film
KOHJIN TSF
KOHJIN TSF
Characteristics
- Air and moisture permeability properties sophisticatedly controlled
- Produced using our original method, this film has air and moisture permeability functions under sophisticated control to add stable exothermic characteristic to portable hand warmers.
- Highly matched with automatic filling packaging
- With the combination of low-temperature sealing properties of the KOHJIN TSF-EU base material and heatproof properties of the nylon unwoven fabric attached, this film exhibits high suitability automatic filling packaging as it withstands high speed processing.
- A fine texture for a good fit with clothing
- With the softness of the base material and the bulky nylon unwoven fabric, this film is such a good fit with clothing that it minimizes discomfort when worn.
- Safe in waste disposal
- This film complies with the JIS S 4100 standard for hazardous substances and can be safely discarded as industrial waste.
Examples of Applications
Packing material for disposable adhesive hand warmers (regular size, small size, etc.), for medical heating devices and for other products requiring air and moisture permeability
Specifications
- Product width: 200 mm to 900 mm
