Effect of Sorption of Organic Volatiles on the Mechanical Properties of Sealant Films

Source

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.
