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.

Parafilm® Grafting Tape

Parafilm® grafting tape is an economical, fast and easy-to-use product that makes plant grafting and budding efforts a breeze for nursery workers, landscapers and gardeners. Apply Parafilm® tape over the usual grafting rubber or tape normally used to hold the union secure until the graft takes hold. And, it may be enough alone to hold the scion of some soft-stemmed species in place.

Parafilm® clear film has the right attributes to ensure your grafting efforts succeed. It is waterproof, flexible, stretchable and self-adhering. It allows gases (oxygen, carbon dioxide, etc.) to pass through, yet offers an excellent moisture barrier. The combination is perfect for grafting which requires a barrier to keep moisture in while allowing oxygen and carbon dioxide to pass through.

Available in clear tape in 1/2 " and 1" wide rolls.
