类纸箱检测要求比较多，如纸箱的加强材料、尺时与公差、压痕、开槽与裁切刀口质量、手挽孔或提手质量、摇盖质量、 钉合质量、 粘合质量、 抗压能力、 机械冲击能能、防潮、防火性能等等都需要满足其规定。

There are many inspection requirements for carton, such as reinforcement material, time and tolerance, indentation, slotting and cutting edge quality, hand hole or handle quality, shaking cover quality, nailing quality, bonding quality, compressive capacity, mechanical impact energy, moisture resistance, fire resistance and so on.

所以总结来讲，重型瓦楞纸箱检测项目主要有耐破强度、戳穿强度、变压强度、空箱抗压能力、抗冲击能力。中抗冲击能力检测主要包括了跌落冲击试验、水平冲进试验、可控水平冲击试验等项目。

Therefore, in summary, heavy corrugated box inspection items mainly include bursting strength, puncture strength, variable pressure strength, compressive strength of empty cases, and impact resistance. The middle shock resistance test mainly includes drop impact test, horizontal impact test and controllable horizontal impact test.
