Note
Measuring conditions: 20°C×65% RH, with the following exceptions
- Oxygen permeability
- 1) 20°C×0%rh
2) 25°C×75%rh MOCON-OXTRAN - Equilibrium water absorption
- 20°C×92%rh
- Water vapor permeability
- MVTR (JIS Z0208 40°C, 90%RH)
The above physical property values are representative values, and not guaranteed values.
2. Gas Barrier Performance
- Bovlon creates a strong barrier against oxygen, carbon dioxide, nitrogen, and other such gases.
- The barrier was maintained even after conducting a flex resistance test (Gelbo flex testing.)
3. Water Vapor Permeability
- Bovlon provides moisture permeability in accordance with temperature and humidity.
4. IR Blocking Property
- Bovlon blocks infrared rays and provides high heat retention.
*Bovlon usage precautions
- Bovlon is hydrophilic. Do not use or store the film in high temperature and humidity. Use Bovlon packaging machines in a humidity controlled room.
- When not in use, tightly wrap Bovlon film rolls in polyethylene film. Do not leave them exposed. Bovlon film rolls should be left inside a temperature and humidity controlled room for 24 hours before they are mounted on a packaging machine.
