Carbondioxyde transmission (CO2 TR) rate of plastic films, laminates, coated papers, Alufoils, etc.
Testing performed with the manometric method acc. DIN 53380 T 2 resp. ISO 15105-1 (Brugger-method), also comparable to ASTM D 1434-procedure M. Usually deviating from the standard as a double determination.

The CO2 transmission rate measures how much carbon dioxide gas passes through a packaging material over a specific period. The test uses the manometric method, where the material is placed between two chambers; one side is filled with CO2, and the pressure increase in the receiving chamber is measured as the gas permeates through the sample.
The resulting value indicates the gas barrier properties of films, laminates, or foils, which is critical for products that release CO2, such as coffee or carbonated beverages. Packaging developers use this data to ensure the material prevents pressure buildup or premature spoilage, thereby maintaining product quality and shelf life.
