Impact of Zinc Oxide Nano Particles, Poly Vinyl Alcohol, and Natural Polymers on Quality Characteristics of Nanocomposite Film

The use of biodegradable films to replace the synthetic polymers prepared from natural has been strongly limited owing their poor barrier and mechanical properties. modification was carried out with a partial replacement polymer, such as PVA (poly vinyl alcohol), increase properties film. addition an active ingredient in form nanoparticles Zinc Oxide (ZnO), enhanced packaging materials compared conventional composite film, which sonication imparted excellent dispersion slurry. film thickness, water vapor permeability, solubility, composite, PVA, ZnO nanoparticle (active film) values differed significantly (p < 0.05) between samples. Z-average diameters slurry, slurry ranged 242.20 1021.03 nanometers (d-nm). PDI zeta potential samples were also analyzed. antibacterial activity showed distinct inhibition against Gram-positive Bacillus cereus Gram-negative Escherichia coli treated counterpart control films. conferred properties, including
