The Fraunhofer Institute for Process Engineering and Packaging (IVV), Freising (Germany), determined the oxygen and water vapor permeability of various foil samples on behalf of Clesana AG. The test report with order number ME-1051-25 documents the test procedure and the measurement results.

Samples tested

To determine oxygen and water vapor permeability, samples of Clesana high-barrier film liners, Clesana Bio high-barrier film liners, and film samples from three competitors were tested.

Summary

Clesana AG commissioned the test in order to have the oxygen and water vapor permeability of its own high-barrier film liners and other film samples from market competitors measured under uniform conditions. The values documented in test report ME-1051-25 for Clesana film liners range from 0.14–2.47 cm³/(m²·d·bar) for oxygen permeability and 1.38–1.55 g/(m²·d) for water vapor permeability. The values of competitors’ products, on the other hand, are many times higher and more permeable.

The high barrier ensures that waste and other contents are securely enclosed. As a result, not only users but also everyone involved in the disposal infrastructure has no contact with the contents of the bag.

Clesana uses these results as a basis for quality assurance and product development and makes the measurement results available in a transparent manner.
