What is WVTR (Water Vapor Transmission Rate)? - Pharma …
Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical. Moisture sensitive foods and … See more There are various techniques to measure MVTR, ranging from gravimetric techniques that measure the gain or loss of moisture by mass, to highly sophisticated instrumental techniques that in some designs can … See more • Bell, L.N., and Labuza, T.P. 2000.

In the USA, g/100in²/day is also in use, which is 1/15 of the value of g/m²/day units. Typical rates in aluminium foil laminates may be as low as 0.001 g/m²/day and in fabrics may measure several thousand g/m²/day. Often, testing is conducted on a sheet of material. premium seed market coupon
