Popis: Thermoplastic starch film (TPSF) and hybrid thermoplastic starch film (HTPSF) were stored for 3 months to study the effect of aging on the mechanical properties and crystalline structure of the starch biopolymer. The alteration of the mechanical properties and crystalline structure of the films were analyzed through tensile test and differential scanning calorimetry (DSC) analysis. The incorporation of the hybrid filler (microcrystalline cellulose + nanobentonite) in the HTPSF has effectively prevented retrogradation happen in the starch structure. In contrary, the TPSF showed high degree of retrogradation resulted in significant decrement in elongation at break which was not observed in the HTPSF after 3 months of aging test.
