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.

In short — AI-generated

This test measures the oxygen transmission rate (OTR) of finished packaging such as pouches, bottles, or moulded parts using a coulometric sensor. A carrier gas flows through the test setup to detect the amount of oxygen permeating through the packaging wall under controlled conditions.

The resulting value indicates the barrier efficiency of the packaging, helping to determine if it provides sufficient protection for oxygen-sensitive products. Please note that this method is only suitable for materials with a high oxygen barrier, as it cannot measure highly permeable plastics like standard PE, PP, or PS.
