The influence of sorption of organic volatiles on the mechanical properties of polymeric sealant films was investigated. Three sealant films were used, a commercial low-density polyethylene, and two developmental films, an ethylene vinyl alcohol copolymer of high ethylene content and a copolyester. Samples of the films were immersed in three different juices (orange juice, apple juice, and tomato juice) for up to 24 days at 22°C. Periodically, film samples were removed from the different juices and the stress-strain properties, heat seal strengths, and impact resistance of the test materials determined as a function of sorbed organic volatile levels or storage time. Statistically significant differences were found in the mechanical properties of the films as a function of sorbant level and storage time. The amount of change varied and was dependent on the film-juice system and the mechanical property evaluated.
