Research on the Interactive Problems and Countermeasures of Food Intelligent Packaging in the Post Epidemic Era

Intelligent packaging is one of the main technologies that achieve to make our lives more convenient in recent decades. People are paying attention to the safeness that packaging can offer, especially during the pandemic. This paper collected and analyzed the research results of intelligent packaging in the field of food in recent years through journals, network reports and other channels before the research. We found several ways of interacting, for such as QR codes, RFID tags and smartphones. Regardless of the progress in the area of food intelligent packaging, some problems appeared, such as the high costs and simplification of the methods. The final discussion states that the interaction way could be more diverse, or more technologies could be used to improve packaging’s efficiency. Further researches and experiments may need in order to fulfill the application of future technologies and progress.
