Cellulose, CNCs and Nanocomposites were characterized. Amorphous non-cellulosic materials were removed from the grape pomace presented values for CrI 64% and 71% and yield 12and 70% in Cellulose and CNCs, respectively. Nanocomposites showed smaller permeability and the addition of5 to 15% CNCs formed more opaquefilms and had improved tensile strength and Young’s modulus. The additionof CNCs from 5 to 15% proved to be effective in improving mechanicalproperties and decreasing water vaporper-meability, important characteristics in food packaging materials. This study provided an effective method to ob-tain CNCs from the agroindustrial waste and open the way to produce high-value starch based nanocomposites.  aBiopolymers  aFood technology  aMechanical properties  aNanocomposites  aPackaging  aBarrier properties1 aSILVA, R.
