High pressure processing of food in modified atmosphere packaging is part of a hurdle concept for prolonging the shelf life of microbiologically sensitive food. As common gases are in a supercritical state during pressure treatment, interactions between gases and packaging materials may occur, endangering packaging integrity by related damages. The aim of the study was to identify failure mechanisms and their dependence on packaging parameters. The development of a new measurement method allowed a quantification of oxygen permeation processes in polymers under pressure.
