Chitosan is an interesting biodegradable and cationic polysac-charide, with a good film-forming ability. Chitosan-based films are tenacious, enduring, extensible, and very difficult to cut. Furthermore, on account of antibacterial activity and non-toxicity, this biopolymer has a high potential as antimicro-bial packaging film. The blending of fish gelatin with chitosan in films hasbeen relatively considered, primarily to improve the film barrier properties.
