Water vapor permeability measures the ability of water vapor to pass through a film material, that is, the rate of water vapor permeability test or moisture permeation test per unit area under a specific vapor pressure difference. This parameter is also known as Water Vapor Transmission Rate (WVTR) or Moisture Vapor Transmission Rate (MVTR) and serves as a key indicator for WVTR test for packaging materials and moisture vapor transmission rate testing.
By studying various water vapor permeability test methods, Labthink has developed a wide range of water vapor permeability testers, covering standards such as ASTM E96/GB 1037 (gravimetric method), ISO 15106-2/ASTM F1249 (infrared sensor method), ISO15106-3 (electrolytic sensor method). As a global leading WVTR testing equipment supplier, Labthink provides the most comprehensive line of water vapor permeation analyzers in the packaging industry.
