Permeability Testing

ORDER FOR carrying-out of test

Packaging, by providing optimal storage and transport conditions, protects the product from deterioration of its properties due to the presence of gases such as oxygen, water vapor or carbon dioxide. Therefore, it is so important to ensure appropriate packaging parameters, depending on whether it is used to protect food products, medical products, pharmaceuticals, cosmetics or agricultural and industrial products.

The parameter defining the ability of oxygen, carbon dioxide and water vapor to penetrate the packaging material is its barrier. The results of barrier measurement can very often be directly related to the stability and shelf life of the packaged product. In addition, they confirm that the packaging, depending on its purpose, meets the appropriate protective properties throughout the storage cycle.

We perform barrier tests of a wide range of plastic packaging materials for the following gases:

OXYGEN O2TR - compliance with ASTM D3985, ASTM F2622, ASTM F1927, ASTM F1307, JIS K-7126, ISO 15105-2, DIN 53380-3

CARBON DIOXIDE CO2TR - compliance with ASTM–F2476

WATER VAPOUR WVTR - compliance with ASTM F1249, TAPPI T557, JIS K-7129, ISO 15106-2

We have TOTALPERM system which allows measurements for both flat samples (foils, laminates) and entire packages (3D adapter).

O2 measurement range for foil: 0.01-7500 cm3/m2x24h/bar (without mask) and 0.2-150000 cm3/m2/24h/bar (with mask)
CO2 measurement range for foil: 0.25-18000 cm3/m2x24h/bar (without mask) and 20-360000 cm3/m2x24h/bar (with mask)
H2O measurement range for foil: 0.002-100 g/m2x24h (without mask) and 0.04-2000 g/m2x24h (with mask)
