Résumé
The global market for packaging materials is expanding significantly. Active packaging is designed to create a unique environment within the package to delay the growth of spoilage organisms and thereby extend the quality of packaged foods. Ionizing technology can be harnessed in the recycling of natural materials to extract biopolymers and bioactive compounds which are then either coated, incorporated, or immobilized onto packaging materials to form active packaging materials. Such materials have been found to extend the shelf life of a variety of foods. Ionizing technologies can be used to improve the quality of natural biopolymers by either grafting materials onto polymers or by crosslinking the polymers. Significant improvements in puncture strength, deformation, and polymerization were achieved when specific packaging films were exposed to defined ionizing doses. Ionizing technology has also been shown to functionalize a variety of biopolymers by substrate activation. It can also be used in the upcycling recycling of cellulose from aseptic packaging wastes as a reinforcement agent of polyester-based composites. Ionizing technologies can play a major role in the crosslinking of protein films and synthetic polymers.
