Antimicrobial packaging of ZnO–Nps infused into CMC–PVA nanocomposite films effectively enhances the physicochemical properties

The objective of this work was to investigate the effect of ZnO nanoparticles (ZnO–Nps) on the physicochemical properties of carboxymethyl cellulose–polyvinyl alcohol (CMC–PVA) films and the release kinetics of the nanoparticles into food simulants were studied. The tensile strength and elongation a...
