Plastic packaging has increased concerns about human health and the ecosystem due to non-biodegradability. Several biopolymers, such as cellulose, starch, and proteins, are being explored, and cellulosic residue from agricultural biomass is suitable to overcome this predicament. Herein, cellulosic residue fibers (ACR) extracted from alfalfa were used to prepare biodegradable films by solubilizing them in ZnCl
