With different shapes and appearances, face masks are mainly categorized into flat face mask, which mostly used in public, and folded face mask with higher efficiency grade for medical or other special uses. And there are different efficiency classification standards in Europe (e.g., FFP2, FFP3), America (e.g., N95, N99), and China (e.g., KN95, KN99). Sandwich structure: spunbond nonwoven + PP meltblown + spunbond nonwoven, is regularly used in face masks, while the filtration efficiency of PP meltblown decides the efficiency class of the face mask.
Mingguan provides premium quality of PP meltblown for face mask application which covers different standard classification globally. OEM service for both flat and folded finished face masks are also available from us.
