Understanding Water Vapor Transmission Rate (WVTR) Testing of Barrier Materials

In this video we provide a simplified explanation of Water Vapor Transmission Rate (WVTR) and the most common WVTR test method used to determine the water vapor transmission rate of variours types of barrier materials (ASTM F1249, ISO 15106-2). It will help you to better understand WVTR and what happens when you are testing a film for water vapor transmission.
