Objective To establish a general 2D figure of corrugated box which meets customers’requirement, and to provide support for the rapid design of corrugated box. Methods According to the type of corrugated box and the size relationship, the influence of factors such as indentation and slot on carton forming was put forward. According to the latest FEFCO standard, the 2D diagram of corrugated box was draw and parameterized based on Solid Edge, and the indentation values of l1 and l2 as well as the correlation dimension were revised. Results The 2D diagram of corrugated box was optimized, and the correlation dimension of different corrugated box was summarized. Conclusion The modified 2D diagram’ s proofing was more accurate, and the parameterized figure could meet the requirements of different customers.
