Water vapor transmission rate (WVTR) of paper and board
Determination of the water vapor transmission rate (WVTR) according to the ASTM F1249 standard. WVTR describes the amount of water vapor that passes through a material over a set period. It is an important quality indicator in food and cosmetics packaging, as an effective moisture barrier is critical to keeping products fresh and preventing them from spoiling.
In this WVTR test, three samples per material are analyzed to ensure the reliability of the measurement. The results are expressed as g/m2/day.
Please disclose the desired temperature (from 15 to 55°C) and the desired relative humidity (from 35% to 90%) when placing the order.
This measurement is applicable for paper and cardboard materials with WVTR values between 0.001 and 1000 g/m2/day.
