With the constantly escalating demand for safe food packaging, utilization of biodegradable polysaccharide-based nanocomposite films is being explored as an alternative to traditional petrochemical polymer (polyvinyl alcohol, polybutylene succinate, etc.). Polysaccharide-based have excellent mechanical properties, water vapor transmission rates, and other physical characteristics. Films can fulfill numerous demands fruit packaging in daily life. Additionally, they be loaded with various types non-toxic non-biocidal materials such bioactive substances metal nanomaterials. These enhance bacterial inhibition reduce oxidation fruits while maintaining fundamental functionality. The article discusses design preparation strategies their application preservation. films, addition materials, mechanisms action are further discussed. In addition, this research crucial preservation efforts both scientific industrial applications.
