Oxygen transmission rate (OTR) of packages, pouches, moulded parts, bottles, etc. (only suitable for barrier materials, see also "i")
The measurement is carried out using the coulommetric, oxygen-specific carrier gas method.
Attention: This is only suitable for packages with a good oxygen barrier. Materials with high permeation coefficients, such as PP, PE or PS cups cannot be measured because the permeation is too high.
at least one for each individual measurement, and ideally a few extra items as spares
