Unverified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87% similarUnverified纸箱克重（如K=A级牛卡）比单看瓦楞层数更影响抗压，同为五层，优质面纸克重高的箱子抗压强度可差一倍84% 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83% similarUnverified面料克重是耐用度关键指标：弹力套面重≥260g/㎡为厚实款不易变形透光，＜200g/㎡的薄套穿几次就松弛且会透出底色81% 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78% similar
