Intelligent packaging has become a new direction of packaging development in the new era. As the basis of intelligent packaging development, new intelligent packaging materials have always been the focus of research. Shape memory polyurethane is a functional material with block structure and excellent shape memory effect. The structure, shape memory principle, synthesis process and development of shape memory polyurethane were introduced firstly.Then the potential application of shape memory polyurethane in intelligent packaging was summarized. Finally，the problems and potential application of shape memory polyurethane in intelligent packaging were indicated in order to provide theoretical basis for further application research.
