Summary A new and fast bioluminescence method for the determination of oxygen transmission rates through plastic films and laminates is described. The method is based on the measurement of in vivo light intensity emitted by luminous bacteria confined in a pouch made of the tested plastic film. The measured light intensity was found to be linearly proportional to the oxygen transmissibility of different plastic films.
