Abstract
The application relates to a fruit and vegetable packaging film based on a MOF material, which comprises the following components: polyvinyl alcohol, modified polylactic acid, Ag@MOF nanoparticles, plant extract, glycerol, and a solvent; wherein the modified polylactic acid is obtained by reaction of acrylamide, double-bond polylactic acid, vinyl acetate and KH570 modified nano-silver particles. Through the synergistic effect of the modified polylactic acid and components such as polyvinyl alcohol, Ag@MOF nanoparticles and plant extract, the mechanical properties, compatibility, antibacterial property, barrier property and preservation performance of the packaging film are significantly improved, the degradability of the material is ensured, and the application has important significance for promoting the development of the fruit and vegetable preservation packaging industry.
