The work aims tointroduce the research progress of biobased polymer packaging and provide a reference for further research on the functionalization of biobased polymer packaging materials. According to the source classification of biobased polymer packaging materials, the research progress of natural biobased polymers, microbially synthesized biobased polymers and chemically synthesized biobased polymers was summarized and the functionalization of these biobased polymers and their applications for food packaging, such as antibacterial, antioxidant, pH-responsive, photo-thermal responsive packaging applications was concluded. The food packaging from biobased polymer has a great application potential in the green food packaging field.
