Product Introduction
Our Medical Meltblown Nonwoven Fabric is a high-performance filtration material manufactured through advanced meltblown technology using 100% virgin polypropylene (PP). Featuring an ultra-fine microfiber structure, this fabric delivers exceptional bacterial filtration efficiency (BFE), particle filtration efficiency (PFE), low breathing resistance, and superior electrostatic adsorption capabilities.
As the critical core filtration layer for medical face masks, surgical masks, and respirators (including N95, KN95, and FFP2/FFP3), our products fully comply with international medical standards such as EN 14683 and ASTM F2100. We offer customizable filtration efficiencies (BFE/PFE/VFE from 95% to 99.9%) and long-lasting electret performance. Backed by stable, large-scale production capacities and strict quality control, we are a trusted medical-grade supplier to healthcare manufacturers worldwide.

Quality Control
Quality is our lifeline. Every production batch undergoes continuous online monitoring and strict laboratory verification prior to release, including:
Incoming Material QA: Melt Flow Index (MFI) and moisture testing for every batch of PP resin.
In-Line Monitoring: Automated laser scanning for web uniformity, weight stability (GSM), and pinhole detection.
Finished Roll Laboratory Testing
- BFE / PFE testing via automated filter testers (TSI 8130A or equivalent).
- Air Permeability / Pressure Drop (Delta P) verification.
- Tensile Strength & Elongation (MD/CD) machine testing.
- Traceability: Every roll is assigned a unique barcode linked to its raw material source, machine settings, and specific QA report.

FAQ
Q: How do you guarantee that the filtration efficiency (BFE/PFE) won't decay during long overseas transit?
A: We use ultra-stable electret formulation masterbatches and high-voltage corona charging technology during production. This permanently traps the ions within the microfibers. Additionally, our rolls are double-sealed in heavy-duty moisture-proof PE wrap to isolate humidity, ensuring static charges remain active for 2 to 3 years under regular warehouse storage.
Q: What international medical standards do your meltblown fabrics comply with?
A: Our fabrics are engineered to pass EN 14683 (Types I, II, and IIR) for the European market, ASTM F2100 (Levels 1, 2, and 3) for North America, as well as NIOSH standards for respirators. We supply official third-party test reports (such as SGS or Nelson Labs) upon contract validation.
Q: Can I get a free sample roll to test on my own mask production machine?
A: Yes, absolutely. We welcome quality evaluations. We can provide free sample rolls (in standard widths like 175mm or 260mm) for your machine trial. Customers only need to cover the international courier shipping fees, which are fully refundable upon your first commercial container order.
Q: What is your Minimum Order Quantity (MOQ) and lead time?
A: For standard white 175mm or 260mm widths at 25gsm, the MOQ is 1 ton. For highly customized specifications, please contact our team. Standard orders are typically dispatched within 7 to 15 working days from our facility.
