Gelatin film has excellent biocompatibility and biodegradability. In addition

the properties of gelatin film could be adjusted according to the application

so gelatin film is applied in many fields. The influences of some additives and preparation on the mechanical

barrier

and biodegradability properties of gelatin film were reviewed in this paper. Commonly

plasticizer could overcome brittleness of gelatin film

decrease mechanical strength and thermal stabilization of gelatin film. Cross-linking could effectively improve mechanical strength and thermal stabilization of gelatin film

and decrease degradability of gelatin. There were chemical

physical and biocompatible cross-linking. Blend with proteins

polysaccharides

lipids could improve properties of gelatin film. The properties of gelatin film could be modified through combination or copolymerization with polymers

in order to meet the application of different fields.
