Meltblown nonwoven fabric is a microfiber-based material made via melting, extruding, and blowing polymer resins (e.g., PP). It features ultra-fine fibers, high porosity, and excellent filtration, making it a core component in face masks, air/water filters, and medical barriers. Its absorbent, lightweight, and breathable properties also suit hygiene products (diapers, wipes) and industrial insulation, meeting diverse protective and functional needs.
