The food packaging sector generates large volumes of plastic waste due to the high demand for packaged products with a short shelf-life. Biopolymers such as starch-based materials are a promising alternative to non-renewable resins, offering a sustainable and environmentally friendly food packaging alternative for single-use products.

(Gelatin-pectin-starch)-(gelatin-pectin)-(gelatin-starch)-(starch-pectin) | Potato | Mentha pulegium and Lavandula angustifolia essential oils | The incorporation of essential oils resulted in films with enhanced antibacterial properties, lower water vapor permeability, and reduced mechanical properties | Food Packaging | [17] |
Carvacrol essential oil-corn starch-montmorillonite-tween 80/Carvacrol essential oil-glycerol-corn starch | Corn | Carvacrol essential oil | The starch-montmorillonite-carvacrol essential oil hybrid films showed antimicrobial behavior against E. coli. | Food Packaging | [18] |
Arrowroot starch-carnauba wax nanoemulsion-cellulose nanocrystals-essential oils from Mentha spicata and Cymbopogon martinii | Arrowroot | Mentha spicata and Cymbopogon martinii | The essential oils from Mentha spicata and Cymbopogon martinii incorporation improved the thermal stability of the films and provided excellent protection against fungi Rhizopus stolonifer and Botrytis cinerea. | Food Packaging | [19] |
Corn starch-thyme essential oil microcapsules | Corn | Thyme | The addition of thyme essential oil microcapsules to starch films increased the opacity, thickness, tensile strength and water solubility. They also showed an inhibitory effect against Botryodiplodia theobromae Pat and Colletotrichum gloeosporioides Penz and extended the shelf life of mangoes up to 10 days at 25 °C. | Food Packaging for mango | [20] |
Corn starch-PVA- neem and oregano essential oils | Pea | Neem and oregano | Starch-PVA films with 6.7% of oregano essential oils exhibited the best physical properties, without significant differences with respect to the starch-PVA matrix, while exhibiting antibacterial activity. | Food Packaging | [21] |
