Unverified85% confidenceDecision RuleTime unknown
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

Unverified定量（g/㎡）反映单层纸的密实程度，普通卷纸单层约13-17g/㎡，数值越高纸越挺实抗撕；结合层数可估算整体厚度，比单看层数更准确89% similarUnverified卷纸标注层数≥3层且单层克重≥16g/㎡（即整卷克重换算后每层实测≥15g）才算高端标准，2层纸擦拭时易破需叠加使用反而更费86% similarUnverified3层纸并非一定比2层好，关键看单张定量（克重），2层高克重（如≥45g/㎡）实际比3层薄纸更耐用不易破86% 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85% similarUnverified3层纸并非一定比2层厚实，部分3层是薄纸叠加，实测单张克重(定量)达到18-20g/㎡以上的2层纸韧性优于薄3层85% similar
