A method to determine the oxygen content and oxygen permeance of composite packages is described. It can be used for packages comprising materials of different permeability, or ones that have pinhole or sealing defects. The method requires little specialized apparatus and is well-suited to the determination of the temperature coefficient of permeance for a package. The results are relevant to the design and quality control of modified atmosphere packaging for respiring fresh vegetables.
