Development of biodegradable films with antioxidant properties for food packaging applications

Researchers at IRTA in Spain developed biodegradable films with antioxidant properties based on Ecoflex® and Ecoflex®-polylactic acid (PLA) containing α-tocopherol and olive leaf extract by blown film extrusion.
The results confirmed the feasibility to produce antioxidant films with Ecoflex and Ecoflex/PLA blend. However, the concentration of antioxidant that can be added to the films is constrained by the changes induced on the physical properties.
The weak interaction between the antioxidants and the polymer matrix would provide a material suitable for food products with a short shelf life. An article about the research is published in Food Packaging and Shelf Life.
