The paper aims to study the application, academic value, design method, innovation, and thinking of AR technology in Lingnan cultural creative packaging design in the context of digital economy. Through analyzing the development status of AR technology and packaging design cases in the context of digital economy, combined with the design practice work "Exploring Xiguan AR", the innovation and thinking of AR technology in the field of Lingnan cultural creative packaging design are explored. In the design process, "AR+ Lingnan Cultural Creativity" is the core of this paper. The development of AR packaging design cannot be separated from the progress of science, technology and digital economy. Augmented reality technology will gradually increase its application in the field of cultural creative industries, especially in the digital inheritance and protection of Lingnan cultural heritage. The application of AR technology in packaging design will be present as a virtual packaging form, and green virtual packaging design concept will be raised.
