In laboratories, Parafilm M sheet is a thermoplastic, self-sealing film that holds moisture loss to a minimum and offers excellent barrier protection to the contents of tubes, flasks, culture tubes, etc.

Available in dispenser box 100mm X 40 metres. (4" X 125')


Permeability Characteristics:

Oxygen (ASTM 1927-98):
150 cc/m d at 23C and 50% RH
Carbon Dioxide (Modulated IR Method):
1200 cc/m d at 23C and 0% RH
Water Vapor (ASTM F1249-01):
Flat: 1 g/m d at 38C 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 (RH) will make a difference in the oxygen permeability.
