This paper introduced the cushion packaging CAD system and its operation process. This system used Visual Basic as the programming language. It could implement many functions, such as the calculation and checking of cushioning pad and corrugated box, data processing and picture displaying, etc. This system improved the database of corrugated cushioned pad and corrugated box. It was convenient for transport packaging design of regular products. The design result of the system would not only satisfy the requirements for products protection in transportation, but also avoid the human error, reduce the destructive test, and shorten the period of development. This system effectively combined computer with packaging technology, and developed design technology of transport packaging both in theory and in practice. It made the complex design process simple and quick.
