Although the specification of packaging box is one of the most important process to be considered before deciding cost in terms of production and logistics, there are no efficient services in our country at this time as such the making decision only through the empirical knowledge. In this research, we have developed the packaging specification design system based on the web online packaging IT service. The developed system was advanced from the existing-inefficient process of deciding the specification of packaging box, and which can decide the specification of packaging box considering the efficiency of logistics through use of IT based tool. Therefore, this study shows applied cases of normalized packaging process through the obtained packaging design simulation program. The packaging specification design system can provide the simulation and user interface. Those could calculate the specification of packaging box(packaging box size, packaging box quantity, packaging box pattern, packaging compressive strength, packaging cost etc.) considering the efficiency of logistics.
