PERMEABILITY TO OXYGEN (O2) AND PERMEABILITY TO WATER VAPOUR (H2O)
Packaging is the interface between the external environment and the product to protect, the choice of packaging materials is critical to ensure food preservation, water resistance and good isolation of sensitive electronics. SERCOVAM offers its customers a personal highly qualified in the tests of permeability to oxygen or water vapor (H2O) to assess the barrier properties of packaging materials and more particularly to measure the diffusion coefficient of gas permeability of films or blister: • Oxygen permeability according to ASTM F2622: Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using Various Sensors • Oxygen permeability according to principles ASTM D3985: Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor and ASTM F1307: Standard Test Method for Oxygen Transmission Rate Through Dry Packages Using a Coulometric Sensor • Water vapour permeability according to principles of ISO 15106-1: Plastics + Films and sheeting + Determination of water vapour transmission rate + Part 1: Humidity detection sensor method or ISO 2528: Sheet materials - Determination of water vapour transmission rate - Dish method.
