Permeation (air, helium, argon, others on request) of plastic films, laminates, coated papers, Alufoils
The method enables permeation measurement of permanent gases according to the non-selective manometric method. The measurement is only possible with dry gas (0% relative humidity).
In short — AI-generated
This test measures the gas permeability of flexible packaging materials like plastic films, laminates, and aluminum foils using a manometric method. The material is placed between two chambers, and the pressure increase caused by gas molecules migrating through the sample is measured under dry conditions.
The resulting value indicates the barrier efficiency of the material against specific gases such as air, helium, or argon. Packaging developers use this data to ensure the material provides the necessary protection to maintain product quality and shelf life.
