A recent study by Pedro Fonte’s group at iBB-BERG (Instituto Superior Técnico, Universidade de Lisboa), in collaboration with Yeungnam University and Kyung Hee University, introduces an innovative biodegradable packaging material that not only protects, it preserves.

The team developed composite films made from poly(butylene adipate-co-terephthalate) (PBAT) and caffeic acid (CA), a natural antioxidant. These films exhibit:

• Outstanding mechanical flexibility
• Strong UV-blocking properties
• Potent antioxidant and antibacterial activity (against E. coli and Listeria monocytogenes)
• Enhanced preservation of vegetables (tested on fresh-cut carrots)

A promising alternative to conventional plastic in active food packaging!

This work exemplifies how natural additives, and biodegradable polymers can create smart packaging that aligns with both food safety and environmental goals.
