Oxygen Transmission Rate
Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.
It relates to the permeation of oxygen through packaging to sensitive foods and pharmaceuticals.
