This paper expounds the new classification and design form of packaging design brought by the development of IOT (Internet of Things) technology, which is characterized by the connection of things. In view of the characteristics of perception and communication between things and things in IOT technology, case analysis method is used to illustrate the characteristics of IOT technology and the changes brought about by the application of IOT technology to packaging design. The application and innovation ways of intelligent packaging design under the background of IOT Technology was proposed. It is pointed out that the technological innovation brought by IOT technology is irreversible. The high-tech elements contained in the design can provide more diversified design forms for packaging design, and also provide more intelligent management mode for brands.
