Oxygen transmission rate (OTR) of films and sheeting
Determination of the oxygen transmission rate of films and sheet-like materials. The test is performed on two parallel samples simultaneously.
Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. Oxygen permeability is typically measured at 23 °C and 0% relative humidity as per standard ASTM D3985. In moist conditions, for example at 38 °C and 90% relative humidity, standard ASTM F1927 is used.
Please disclose the desired temperature (from 10 °C to 38 °C) and relative humidity (either 0% or 20% to 90%) upon ordering.
This measurement is suitable for films with OTR values between 0.05 to 20 000 cm3/(m2 * day).
