With the development of express industry, express packaging brings about environmental pollution and waste of resources, thus, based on the recyclable development concept, shared packaging design mode has become an effective path for sustainable development under the Internet platform. Using literature research, theoretical elaboration, combined with the analysis of design knowledge, the sharing mode of "shared packaging" was studied, that is, the concept of realizing sustainable development by sharing packaging resources. Under the mode of "Internet plus", how to promote users' participation in green consumption, how to achieve the application of shared packaging and effective operation of shared packaging management system remain to be solved for achieving sharing mode of shared packaging. Shared packaging design mode should promote the sharing of packaging resources and realize the sharing of packaging boxes under the Internet platform, which conforms to the characteristics of eco-environment aesthetics and sharing economy and the multiple benefits of economy and ecology. The path of sustainable realization of shared packaging is to advocate green packaging consumption behavior, packaging sharing structure, and shared packaging operation mode in sustainable development, which has certain reference value for the theoretical research and practical development of shared packaging under the data sharing platform.
