Development of biodegradable flexible films of starch and poly(lactic acid) plasticized with adipate or citrate esters

► We tested adipate and citrate esters as plasticizer in starch/PLA films production. ► The films were characterized by FTIR, SEM and mechanical properties. ► Films of PLA with high TPS content using blow extrusion were obtained. ► Production of films was possible due to PLA plasticization. ► Adipate esters were the best plasticizer for PLA.
