This study intended to provide biopolymer films used as food packaging, which will result in reducing environmental pollution produced by the activities of synthetic food packaging. We used zinc oxide nanorods (ZnO-nr) and we prepared nanocomposite films by means of solvent casting. FTIR and SEM were employed to characterize the final films. SEM images revealed that ZnO-nr particles were homogenously distributed throughout the film surface. The thermal, optical, and heat sealability properties of the films were also examined. Adding ZnO-nr signifi cantly reduced oxygen permeability and heat sealability. The semolina films’ UV absorbance was highly impacted by the degree of ZnO-nr addition. The nanocomposite films absorbed above 90% of the near infrared spectra. In addition, the zeta potential revealed the surface charge of ZnO-nr had a negative charge of about -33.9 mV
