纸箱克重（g/㎡）比瓦楞层数更能反映抗压能力，同为3层楞，纸板克重从300g提升到500g，抗压强度可翻倍，选购时优先看纸板厚度而非只看层数

Unverified瓦楞纸箱的抗压强度与克重（g/㎡）相关，同为五层，高克重（如280g以上面纸）比低克重更耐堆叠，购买时可关注是否标注抗压/耐破指标87% similarUnverified克重（定量）比层数更能反映用料，同为3层的抽纸克重可从12g/㎡到16g/㎡不等，克重高的更厚实耐用不易破84% similarUnverified抽纸看'定量'（g/㎡）比看层数更准，单层定量≥18g/㎡才够韧不易破，很多3层薄纸实际用纸量比2层加厚款还少83% similarUnverified克重（定量）比层数更能反映实际用量，同样3层纸，克重从13g到23g/张不等，低克重3层实际不如高克重2层耐用83% similarUnverified纸箱克重（g/m²）反映纸张厚度，五层箱面纸克重通常在150g以上，用手指按压箱面不易凹陷、瓦楞排列紧密的更耐压82% similar
