Material -Meltblown


This is main important material for disposable/KN95 mask, standard filtering effect has to achieve 95%. Our KN95 is using two layers of meltblown to ensure filtration, other manufacturer may using only one layer. Then, our KN95 include 5 layers, others are mostly 4 layers.


Nonwoven

 

Market has S and SS levels:


S nonwoven

Mainly used for packing industry, more harder

SS nonwoven

Mainly used for hygienic industry, more softer


Our KN95 is using two layers of SS nonwoven, however, some mask manufacturer is

using both in S nonwoven or SS+S in a mask. SS nonwoven cost is around 4% higher than S nonwoven.
