AB Fully biobased edible films were prepared using native potato starch  plasticized with glycerol and further reinforced with catechin (Cat) and  starch nanocrystals (SNC) obtained by acidic hydrolysis from waxy maize  starch granules. The thermal stability of starch nanocrystals obtained  at different pH was studied, resulting on a decreasing in thermal  stability at higher pH values. The X-ray diffraction patterns of the  plasticized reinforced materials display complete destructuration of  starch by solvent casting process. Plasticized films showed lower onset  degradation temperatures than non-plasticized starch film. The reduction  of the inter- and intra-molecular bonds interaction within the polymer  matrix due to glycerol presence leads to a decrease of the thermal  stability of the whole system. On the other hand, Cat and SNC produced  an increase on the thermal stability of the bionanocomposites delaying  the beginning of the thermal decomposition of starch/glycerol systems of  about 20 °C. The mechanical performance was also improved in the  ternary bionanocomposite edible films. All the edible films were fully  disintegrated in compost conditions suggesting their possible  applications as biodegradable edible films for packaging.
