The work aims to introduce the research status of bio-based additives for plastic food packaging and to provide some reference and basis for the selection and use of safe and green bio-based additives for packaging. By consulting, analyzing and summarizing literatures, the classification, characteristics and application range of bio-based additives for plastic food packaging were reviewed, and they were classified according to the raw materials of bio-based additives. Bio-based additives for plastic food packaging mainly included bio-based plasticizers, antimicrobials and antioxidants. The characteristics, application and research status of all kinds of bio-based additives were introduced. Bio-based additives are in the stage of rapid development. With the country's attention to green packaging and biodegradable packaging, as well as the "restricting plastic order" issued subsequently, it is expected to realize the effective replacement of traditional additives. Its application prospect and development trend in plastic food packaging have great potential.
