WebVapor Transmission Rate (WVTR) of less than 5 × 10-4 g/m 2/day at 23°C. However, validating WVTR measurements below 10-3 g/m 2/day is difficult and/or time consuming due to limitations on currently available measurement equipment and techniques. The best determinant to ensure that the WVTR performance is adequate is to test the actual WebFACTORS AFFECTING WVTR As with oxygen transmission rate (OTR), WVTR is affected by structural elements of films. Permeation theory, based on Henry’s and Fick’s laws, tells us the movement of a gas through a film is actually a three-step process: adsorption – by which the gas dissolves in the film matrix at the higher concentration side,
