Polysaccharide-based films cannot replace petroleum-based food packaging due to their poor mechanical properties, and the lack of antibacterial properties also makes it difficult to extend the food shelf life. Herein, we used the Schiff base reaction and zinc ion (Zn2+) complexation on carboxymethyl...
