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83% similarUnverified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82% similarUnverified纸张越厚越挺括高档，但克重超过300g后难以折叠成盒且需模切，做包裹纸（非盒型）时250g以上会开裂，包裹用途反而应选80-120g薄纸82% similarUnverified五层AB瓦楞箱典型箱壁总厚度约6-7mm，三层单瓦楞约3mm；用手指按压箱壁，能明显感到硬挺回弹的通常为合格厚度，一压即扁多为薄纸偷工80% similarUnverified台置立式纸巾架看重稳定性，底座重量≥400g或底座直径≥12cm的单手抽取不倒；轻质塑料款单手取纸时整体会被带起，需双手操作80% similar
