Water vapour transmission rate (WVTR)

AMETEK MOCON AQUATRAN 3/34 H

The water vapour barrier keeps dry products (biscuits, crisps) from going soft and moist products from drying out and losing weight; it also prevents condensation inside the pack. It is measured alongside OTR when validating a shelf life.
