Parafilm M® FILM Performance Characteristics

Permeability Characteristics:

  • Oxygen (ASTM 1927-98):
    • 150 cc/m² d at 23°C and 50% RH
  • Carbon Dioxide (Modulated IR Method):
    • 1200 cc/m² d at 23°C and 0% RH
  • Water Vapor (ASTM F1249-01):
    • Flat:
      • 1 g/m² d at 38°C 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.

Effects of Common Reagents:

  • Hydrochloric acid conc. (12N) dil. (5N) - no apparent effect in 24 hours
  • Sulphuric acid conc. (36N) dil.(5N) - no apparent effect in 24 hours
  • Nitric acid conc. (16N) dil. (5N) - no apparent effect in 24 hours
  • Sodium hydroxide conc. (22%) - no apparent effect in 24 hours
  • Ammonium hydroxide conc. (28% NH3) - no apparent effect in 24 hours
  • Potassium permanganate:
    • 5%: no apparent effect except permanent dark brown coloration in 18 hours
    • 0.1%: same as 5% but slightly less color
    • Iodine solution 0.1N: no effect except brown staining in 18 hours
  • Salt (NACL) solution 20%: no apparent effect in 24 hours
  • Ethyl Alcohol 95%: no apparent effect except some face whitening in 24 hours
  • Isopropyl alcohol 99%: no apparent effect in 24 hours
  • Not recommended for use with chorinated, non-polar aliphatic and aromatic solvents

Film becomes soft and sticky at about 130°F to 150°F (68°C)
