Permeation of water vapor, carbon dioxide, and oxygen in polymeric materials (original) (raw)

This research investigates the permeation properties of water vapor, carbon dioxide, and oxygen in polymeric materials used for food and beverage packaging. It emphasizes the importance of mass transfer characteristics in preserving product quality by controlling the transport of gases and vapors through packaging materials. The study presents methods, including quasi-isostatic and isostatic approaches, for measuring these permeation characteristics, and discusses how they impact shelf life by affecting the internal environment of packaged products.
