Plasticized PLA films for active food packaging

23 January 2017

Researchers at the University of Alicante in Spain analyzed fully bio-based and biodegradable active films based on poly(lactic acid) (PLA) blended with poly(3-hydroxybutyrate) (PHB). They incorporated lactic acid oligomers (OLA) as plasticizers and carvacrol as active agent and fully characterized their functional properties for antimicrobial active packaging.
PLA_PHB films showed good barrier to water vapor, while the resistance to oxygen diffusion decreased with the addition of OLA and carvacrol. The antioxidant and antimicrobial activities of the proposed formulations increased by the presence of carvacrol. An article about the research is published in Food and Bioprocess Technology.
