摘要：

The bottom of a kind of flexible packaging container folding forming was taken as the research object.By analyzing the structure characteristics of the packaging film folding forming process,the theoretic relations among the forming device major structure parameters were established.The influence of the main structure parameters was discussed and confirmed based on basic experiment.Further multi-objective optimization of the parameters design was carried out using Pro/E to get preliminary results of the theory design.The purpose was to provide reference for folding forming device design.
