In the context of emerging global concerns with synthetic plastic packaging, alternative natural biodegradable packaging materials are gaining increasing attention for food packaging applications; The synthesis of metal and semiconductor nanoparticles is an expanding research area due to the potential applications in the development of novel technologies in this field. In the present study, a simple and eco-friendly synthesis of zinc oxide nanoparticles (ZnO NPs) using leaf extract of Mentha pulegium has been used. The structural properties of synthesized nanoparticles were investigated. The XRD data confirmed the crystalline nature of the nanoparticles with the average crystallite size calculated across 45 nm. Synthesized NPs were embedded into a chitosan film. Prepared flexible film exhibited strong blue emission under UV radiation with an increased shelf life when surface-coated over the fruits by preventing the decaying caused due to food pathogens. These results indicated that prepared samples can potentially be used as alternative natural packaging for food preservative applications.
