In order to train the practical talents and to meet the needs of Packaging Engineering personnel knowledge structure on the premise of ergonomics requirements, the product design as the core application of ergonomics program is analyzed, combined with packaging engineering course on ergonomics with appropriate adjustment, a suitable packaging engineering professional teaching system for ergonomics is formed. On the teaching content and teaching methods, the idea of switching from theory lecturing oriented to case study oriented is suggested.
