In the modern world, all manufacturers strive for the optimal design of their products. This general trend is recently also observed in the corrugated board packaging industry. Colorful prints on displays, perforations in shelf-ready-packaging and various types of ventilation holes in trays, although extremely important for ergonomic or functional reasons, weaken the strength of the box. To meet the requirements of customers and recipients, packaging manufacturers outdo each other with new ideas for the construction of their products. Often the aesthetic qualities of the product become more important than the attention to maintaining the standards of the load capacity of the packaging (which, apart from their attention-grabbing functions, are also intended to protect transported products). A particular flaps design (both top and bottom) and its influence on the strength of the box are investigated in this study. An updated analytical-numerical approach is used here to predict the strength of packaging with various flap offsets. Experimental results indicated a significant decrease in the static load-bearing capacity of packaging in the case of shifted flap creases. The simulation model proposed in our previous work has been modified and updated to take into account this effect. The results obtained by the model presented in this paper are in satisfactory agreement with the experimental data.
在现代社会，所有制造商都在努力实现其产品的最优设计。最近，这种总体趋势在瓦楞纸板包装行业也有所体现。展示架上的彩色印刷、上架即售包装上的穿孔以及托盘上各种类型的通风孔，尽管出于人体工程学或功能方面的原因极为重要，但却会削弱纸箱的强度。为了满足客户和收货人的要求，包装制造商们竞相推出有关其产品结构的新创意。通常，产品的美学品质变得比关注保持包装承载能力标准更为重要（这些包装除了具有吸引眼球的功能外，还旨在保护运输的产品）。本研究对一种特殊的折叶设计（顶部和底部）及其对纸箱强度的影响进行了研究。这里采用了一种更新的分析 - 数值方法来预测具有不同折叶偏移量的包装强度。实验结果表明，在折叶折痕偏移的情况下，包装的静态承载能力显著下降。我们之前工作中提出的模拟模型已进行修改和更新，以考虑这种影响。本文所呈现模型获得的结果与实验数据吻合良好。
