Nowadays, new bio-based materials are developed in order to partially substitute syn-thetic ones. Starch is a good candidate because of its availability, biodegradability, and low cost. Main disadvantages of thermoplastic starch (TPS) materials are related to their poor me-chanical properties and moisture absorption. Addition of natural fillers or mineral particles to improve their final properties is an interesting alternative [1]. In this sense, talc particles can be used to reinforce different kind of matrixes mainly due to its laminar morphology, as well as, its nanometric size thickness [2]. The aim of this work was to develop films of TPS con-taining talc nanoparticles with proper functional properties for food packaging applications.
