Permeability Characteristics

  • Oxygen (ASTM 1927-98): 150 cc/m2 d at 23oC and 50%RH
  • Carbon Dioxide (modulated IR Method): 1200 cc/m2 d at 23oC and 0%RH
  • Water Vapor (ASTM F1249-01):
    Flat: 1 g/m2 d at 38
    oC and 90%RH
    Creased: same as flat
  • Note: Because of low water permeability and the insensitivity of this material to moisture vapor, it is unlikely that differences in relative humidity will make a difference in the oxygen permeability.
