| Résumé : |
Plastic waste is of great concern to consumers and householders, so that immediate action is requird from the food packaging industries to develop innovative, reusable, recyclable and environment-friendly materials preferably derived from natural resources. This research focuses on polyvinyl alcohol (PVC) bionanocomposite films as a potential sustainable packaging material with overall good mechanical and barrier properties, as well as water resistance, particularly for acidic and lipidic foodstuffs. |
