Unverified看纸巾克重（定量）而非只看层数：部分3层纸压得薄，实际克重可能不如优质2层，单包克重=定量×面积×层数，认准整袋净重84% similarUnverified层数越多越厚实但同价下总克重不变，等于每张用纸更少更快耗完；追求耐用不如直接看每包总克重（如8包×130抽约需≥110g/包）83% similarUnverified瓦楞纸箱克重（如K=K纸/A=A纸）比层数更影响承重，同为三层，300g以上面纸的箱子比200g普通箱承重高出一倍，购买时应问明纸质等级而非只看层数81% similarUnverified克重直接决定纸巾厚实度：单张有效克重≥45g/㎡为优质，＜35g/㎡则偏薄易破。选购时用总重量除以张数抽数判断，标称'加厚'但不标克重的谨慎81% similarUnverified白牌纸巾克重要看单张实际克重而非总重，合格抽纸单层克重约13-16g/㎡，3层抽纸单张重量约0.6-0.9g，用手撕对光看纤维分布均匀无孔洞的克重更实78% similar
