The impact of perforation patterns on the compressive strength of cardboard packaging is a critical concern in the packaging industry, where optimizing material usage without compromising structural integrity is essential. This study aims to investigate how different perforation designs affect the load-bearing capacity of cardboard boxes. Utilizing finite element method (FEM) simulations, we assessed the compressive strength of packaging made of various types of corrugated cardboards, including E, B, C, EB, and BC flutes with different heights. Mechanical testing was conducted to obtain accurate material properties for the simulations. Packaging dimensions were varied to generalize the findings across different sizes. Results showed that perforation patterns significantly influenced the compressive strength, with reductions ranging from 14% to 43%, compared to non-perforated packaging. Notably, perforations on multiple walls resulted in the highest strength reductions. The study concludes that while perforations are necessary for functionality and aesthetics, their design must be carefully considered to minimize negative impacts on structural integrity. These findings provide valuable insights for designing more efficient and sustainable packaging solutions in the industry.
穿孔图案对硬纸板包装抗压强度的影响是包装行业的一个关键问题，在该行业中，在不损害结构完整性的前提下优化材料使用至关重要。本研究旨在调查不同的穿孔设计如何影响纸箱的承重能力。利用有限元方法（FEM）模拟，我们评估了由各种类型瓦楞纸板制成的包装的抗压强度，包括不同高度的E、B、C、EB和BC楞。进行了力学测试以获取模拟所需的准确材料特性。改变包装尺寸以将研究结果推广到不同尺寸。结果表明，穿孔图案显著影响抗压强度，与未穿孔包装相比，强度降低幅度在14%至43%之间。值得注意的是，多面穿孔导致强度降低最多。该研究得出结论，虽然穿孔对于功能性和美观性是必要的，但必须仔细考虑其设计，以尽量减少对结构完整性的负面影响。这些发现为该行业设计更高效、更可持续的包装解决方案提供了有价值的见解。
