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).

Suitable sample matrices

Films composed of different materials and coated surfaces such as cardboard. The material surface needs to be smooth. Maximum thickness 2.5 mm. The expected OTR value should be between 0.05 and 20 000 cm³/(m² * day).

Minimum sample amount

Two sheets sized 12 cm x 12 cm. Preferably a few extra samples in addition to these.

Typical turnaround time

3 weeks after receiving the samples

Detection limit
