The work aims to review the principle, characteristics and research progress in gas sensitive smart packaging labels. The research status and application of leakage indicator, freshness indicator and radio frequency identification labels in gas sensitive smart packaging were summarized. The classification and production method of smart packaging oriented to CO2 gas monitoring and identification were emphatically elaborated, and the application of CO2 sensor in gas sensitive smart packaging was elaborated. In recent years, a large number of research results in smart packaging labels have promoted the rapid development of the food preservation packaging industry. Gas sensitive smart packaging can effectively detect and monitor the quality and safety of packaged food, and played an important role in promoting the informatization and intelligentization of packaging technology. CO2 sensor not only has a wide range of applications in food freshness smart monitoring, but also is the development direction of future food preservation packaging technology.
