The work aims to promote the development of intelligent packaging technology and further expand the function and application field of intelligent packaging. The application status of intelligent packaging technologies such as indicators, barcodes, radio frequency identification, augmented reality and sensors was summarized. The market demand for intelligent packaging and the opportunities and challenges were analyzed in detail, and the future research direction was proposed. Intelligent packaging combines new science and technology on the basis of traditional packaging, which increases the function of packaging, and enables the intelligent packaging to have broad development prospects. However, intelligent packaging is still at the start-up stage, and has disadvantages such as high cost, insufficient safety, environmental pollution and application limitation. It is necessary to further develop new technologies and new environmentally friendly materials and to strengthen information interaction by analyzing the needs of intelligent packaging and exploring future research directions.
