[0002] In the fierce market competition, cost control is the key to the survival and development of enterprises. The price of packaging materials accounts for the main part of the cost of packaging boxes. Therefore, improving the utilization rate of cardboard has become an important way for enterprises to reduce costs. Automatic design technology optimizes design solutions and reduces waste generation, thereby improving the utilization rate of cardboard and reducing production costs. Automatic design technology reduces the impact of packaging cartons on the environment by optimizing carton structure and reducing material waste. This design method that conforms to the concept of environmental protection helps enterprises establish a good image in the market and win the favor of consumers.
