Its major elements of design include colour, picture, modelling, material and characters, etc. which can not only meet people’s aesthetic demand, but also communicate the product information effectively. The visualization of effective information communication utilizes the acute visual perception to help consumers obtain and understand the relevant product information, including visual communication of of declarative knowledge and procedural knowledge. Driven by cognitive motive, comsumers translate the information into declarative knowledge and procedural knowledge of the products via communicating the packaging information into consciousness level.
