3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

Unverified3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95% 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87% similarUnverified纸巾看克重而非层数：3层薄纸不一定比2层厚纸好用，单张克重（约13-17g/㎡为常见优质区间）更能反映实际厚度和吸水性86% 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86% similarUnverified看『克重』而非单纯看层数：优质原生木浆纸巾单张克重通常在13-16g/㎡，同样是3层，克重高的更厚实耐用，低于12g的3层纸往往偏薄易破86% similar
