In this research, the effects of matrix variability and thickness on the properties of aflexible nanocomposite film were investigated. The nanocomposite film was preparedfrom the blends of 1 kg cassava starch, 45–55% (w/v) glycerol and 0–2% (w/v) zincnanoparticles in thickness ranging from 15 −17 µm. The barrier, mechanical, and thermalproperties were determined experimentally. The optimal effects of the thickness and thematrix variability on the properties were determined using Response SurfaceMethodology. Results showed that the barrier properties increased with glycerolconcentration but decreased with thickness. Reduced modulus and tensile strengthincreased with an increase in the matrix variability. The film was thermally stable up to60.43oC with only 2% degradation. The optimal film contains 55% glycerol, 2% zincnanoparticles with a thickness of 17 µm at a desirability index of 0.95. This can thereforebe essential for industrial application
