Oxygen / Gas / Water Vapor Permeability Testing Equipment and Permeation Testing for Plastic Films and Sheet Materials

Gas permeability is the ability of a barrier material to allow gases (O2, N2, CO2 etc.) to permeate through it in a specific time. Gas permeability may vary with temperature, humidity, pressure and specimen thickness.

Water vapor permeability is a measure of the passage of water vapor through a membrane. It is the rate of water vapor transmission per unit area per unit of vapor pressure differential under test conditions.
