Packaging is a means of ensuring safe and efficient delivery of the goods is sound condition to the ultimate consumer, supplemented by efficient reuse of the packaging or recovery and/or disposal of the packaging material at minimum cost.
Fresh-cut produce continues to be one of the fastest growing segments of food retailing and while conventional film packaging is suitable for lettuce and prepared salads, it cannot cope with the high respiration rates of pre-cut vegetables and fruit, leading to early product deterioration. In the USA, novel breatheable polymer films are already in commercial use for fresh-cut vegetables and fruit. Landec Corporation supplies Intellipac packaging films that are acrylic side-chain crystallisable polymers tailored to change phase reversibly at various temperatures from 0-68°C. As the side-chain components melt, gas permeation increases dramatically, and by further tailoring the package and materials of construction, it is possible to fine tune the carbon dioxide to oxygen permeation ratios for particular products. The final package is ‘smart’ because it automatically regulates oxygen ingress and carbon dioxide egress by transpiration according to the prevailing temperature. In this way, an optimum atmosphere is maintained around the product during storage and distribution, extending freshness and allowing shipping of higher quality products to the consumer.
