The work aims to discuss the category, technology and research progress of different edible packaging films and provide technical support and scientific basis for development and application of this material. With edible film as a research subject, the kinds, properties, preparation methods and application status of different edible food such as edible polysaccharide membrane, edible protein membrane, edible lipid membrane and edible composite film were analyzed. The research on the development and performance of edible packaging film has been more and more in-depth and has made some achievements, but there are still many kinds of performance defects that limit its wide application. The research and application of edible packaging film is an important direction of food science and technology development in the world. At present, a lot of experiments and analysis are required from the research and development of materials to practical application in packaging. The development of edible film materials which has excellent performance with environmental friendliness and biosafety not only accords with the main research trend of packaging materials, but also has broad application prospect and market value.
