Eco-friendly multilayer films with biodegradable properties for sustainable packaging
Developing compostable multilayer films using biopolyesters and water-soluble barrier layers for sustainable food packaging. These films promise to reduce environmental impact by offering fully compostable and enzymatically deconstructable packaging solutions.
Overview
The University of Massachusetts Lowell is pioneering the development of eco-friendly multilayer films designed for sustainable food packaging. These films utilize biodegradable polymers to create a packaging solution that aligns with circular economy principles. By combining polyvinyl alcohol (PVOH) and poly(3-hydroxybutyrate-co-valerate) (PHBV), this research aims to provide packaging with effective barrier properties against moisture and gases while ensuring full compostability and enzymatic deconstructibility.
