The work aims to design a management system for the product packaging design method regarding the shortage of product packaging design method management and the serious phenomenon of repeated design. According to the characteristics of products and the influence of the external environment in the process of circulation, the coding technology was used to summarize and grade the packaging characteristics of products, and the product packaging characteristics were divided into high and low correlation characteristics. On this basis, the classification and management of packaging design methods were achieved. The system mainly consisted of method uploading module, method retrieval module, user management module, method management module and reward system. In uploading the packaging design method, the corresponding product packaging characteristics should be entered simultaneously. The method retrieval module mainly adopted the coding technology, rule inference technology and similarity calculation to realize the intelligent retrieval of product packaging design method. The system can conveniently upload and retrieve the product packaging design methods according to different requirements, which optimizes the packaging design process and reduces repeated labor.
