The aim of this study was to develop poly (lactic acid) and chitosan-based films and to examine the effect of cellulose nanocrystal (CNC) as nanofillers on the properties of the films. The biofilms were prepared by solvent casting method. The physical and mechanical properties of the resulting films were examined. SEM analysis showed that the surface of PLA/Cs films smoother when 1% and 2 % of CNC were added. The results for percent of water absorption of the films increased with increasing amount of CNC in PLA/Chitosan matrix. Tensile test results indicated higher TS value by incorporation of 2% of CNC. However, the PLA/Chitosan-CNC films at 3% and 4% CNC concentration exhibited a decreased TS value. PLA/Chitosan films were improved with the addition of a small amount of CNC resulting in PLA nanocomposite, which will be further evaluated for fruit packaging applications. The data obtained through this research could contribute to the establishment of a biofilms with improved the physical and mechanical properties promising significant advantages in term of longer storage life, maintaining safety, and keeping quality of a product especially in fruit packaging.
