Abstract
A packaging film containing a protein, a plasticizer, and a reducing agent is provided. Also provided is a coating layer for use with the packaging film, the coating layer containing wax particles, ethylcellulose, and an emulsifier. The film is prepared by a method comprising the steps of: mixing the protein with water to form a first mixture; obtaining the supernatant from the first mixture; adding the plasticizer and reducing agent to the supernatant to form a second mixture; and drying the second mixture to form the film. The coated film is prepared by a method comprising the steps of: melting the wax to form molten wax; adding the emulsifier and solvent to the molten wax to form a third mixture; homogenizing the third mixture to form an emulsion; adding ethylcellulose to the emulsion to form a coating solution; and applying the coating solution to a film to form the coated film.
