has mechanical strength and flexibility that are comparable to synthetic polyethylene film commonly used for food packaging. The composite film also effectively blocks ultraviolet light, hence slowing down the degradation of food products as a result of oxidation and photochemical deterioration reactions.
Laboratory experiments showed that the shelf life of bread samples packaged with chitosan-based GFSE composite films was two times longer than those packaged using synthetic packaging films.
