Functional alginate-chitosan packaging nanofilms enhanced with calcium chloride and in situ synthesized ZnO@MgO nano-heterostructures
The use of biodegradable materials in food packaging has gained increasing attention as a sustainable alternative to conventional plastics. In this study, calcium chloride-loaded nanofilms were developed using sodium alginate (NaAlg) as the primary polymer matrix, with chitosan (Ch) added at varying concentrations, res...
