Abstract In this study, active nanofilms were developed using basil seed mucilage (BSM) containing zinc oxide nanoparticles (ZnONPs), according to casting method. Different amount of ZnO-NPs at the range of 0% (control), 0.1, 0.25, and 0.5% were incorporated into BSM film, then the physical, permeability, mechanical, thermal, and antimicrobial properties, as well as color index of fabricated films were examined. The results showed that moisture content, water absorption, water solubility, water vapor permeability (WVP), melting temperature ( Tm), glass transition temperature ( Tg) decreased with increasing the amount of ZnO, while the melting enthalpy of films increased (P 0.05). A significant difference was seen in the control group compared to the experiments containing 0.25% and 0.5% NP (P
