目的 优化折叠纸盒结构与拼版方式， 提高纸板利用率。方法 基于纸盒拼版影响因素， 优化拼版设计方案。结果 在实际生产中， 需根据纸盒结构灵活选择拼排方式， 纸板尺寸及纹向也是制约拼版的关键因素， 根据拼版需求， 可对折叠纸盒结构进行局部、 整体、 综合等结构优化策略， 使其结构合理、 排版紧密。结论 折叠纸盒结构拼版设计需综合考虑各方面影响因素， 在可实施的前提下得出最优拼版方案。

The aim of this work was to optimize the structure and layout of folding carton to improve the utilization rate of paperboard in production. The layout design schemes of folding carton were optimized based on the layout influencing factors. In actual production, the layout scheme should be flexibly chosen according to the carton structure. The paperboard size and grain were also key factors for layout scheme. According to the demand of layout, part, overall, or comprehensive structure optimization strategies could be used to modify the folding carton structure, resulting in reasonable structure and compact layout. In conclusion, layout design of folding carton needs comprehensive consideration of various factors, and then the optimal layout scheme can be proposed in the premise of implementation.
