Sustainable food barrier packaging from seaweed biopolymers
Researchers at the University of Hawaiʻi at Mānoa are developing sustainable food packaging films, coatings, and laminates from seaweed-derived biopolymers. Leveraging expertise in algae cultivation and biomaterial engineering, the team aims to deliver cost-effective, eco-friendly packaging with enhanced moisture and oxygen barrier properties for perishable food preservation.
Overview
This solution leverages seaweed biopolymers to create sustainable food barrier packaging materials such as films, coatings, and laminates. Seaweeds are highly productive photosynthetic organisms that generate valuable biopolymers at low cost, offering an eco-friendly alternative to conventional petroleum-based packaging. The approach addresses growing demand for sustainable preservation solutions that reduce environmental impact while maintaining food safety and quality.
