Product Overview
Premium Meltblown Nonwoven Fabric is engineered from 100% virgin polypropylene through an advanced extrusion process. By utilizing high-precision manufacturing lines and real-time thickness monitoring systems, we produce ultra-fine microfibers measuring 1 to 5 micrometers. This specific structure delivers an optimal balance of maximum filtration efficiency, exceptionally low pressure drop (inhalation resistance), and long-lasting electrostatic stability.
Product Features
High Filtration & Low Pressure Drop: Engineered with ultra-fine three-dimensional web structures that maximize particle capture while maintaining superior air permeability and low breathing resistance.
Long-Lasting Electret Charge Stability: Supports advanced Corona and Hydro-charging electret treatments, ensuring the electrostatic charge remains highly stable without significant decay over extended storage.
Certified Microbe & Particulate Barrier: Extensively tested to meet high Bacterial Filtration Efficiency (BFE >= 99%) and Particulate Filtration Efficiency (PFE >= 95% or 99%) standards.
Superior Web Uniformity: Advanced automatic die technology guarantees consistent fiber distribution, uniform weight (GSM), and predictable performance during high-speed automated mask and filter conversion.
Excellent Tensile Strength: Optimized Machine Direction (MD) and Cross Direction (CD) tensile properties to prevent tearing during high-tension industrial processing.
100% Virgin Polypropylene: Made from premium, eco-friendly, recyclable polypropylene with zero toxic additives. It is completely odor-free and safe for skin contact.
Chemical & Thermal Resistance: High resistance to acids, alkalis, and many industrial solvents, making it suitable for harsh chemical filtration environments.

Quality Control & Laboratory Verification
Quality assurance is handled as an active empirical practice. Every manufacturing batch undergoes full traceability testing verified by our internal advanced laboratory:
Filtration Performance Verification: Validated using the TSI 8130A Automated Filter Tester (the global gold standard used by major international standard labs) to guarantee pinpoint accuracy for BFE/PFE and resistance readings.
Online Mass Uniformity Control: Constant web monitoring utilizing non-contact Beta-Gauge sensors to detect and fix any localized GSM deviations across the entire layout instantly.
Mechanical Integrity Testing: Electronic Tensile Strength Testers determine accurate Elongation and Breaking Strength in both Machine Direction (MD) and Cross Direction (CD).
Microscopic Validation: Regular Fiber Diameter inspection using high-resolution Scanning Electron Microscopy (SEM) to verify consistent 1–5 micron sub-micron structures.
Full Batch Documentation: Every shipment is accompanied by a Factory Certificate of Analysis (COA) mapping batch numbers directly to testing performance metrics.
Packaging, Shipping & Storage Protocols
Preservation Packaging: Rolls are individually wrapped in heavy-duty moisture-proof PE film, followed by specialized vacuum-sealing to protect the electret electrostatic charge against ambient humidity during long ocean transits.
Palletization & Container Optimization: Dispatched on export-standard, fumigated pallets secured with multi-layer stretch wrap and corner protectors to ensure zero edge-crushing.
Worldwide Logistics Capabilities: Facilitating seamless global delivery via FCL/LCL Ocean Freight, Air Freight for urgent trials, and intermodal Rail Transport. Full support for standard international trade terms including FOB, CIF, DDP, and CFR.
Storage Requirements: To maintain peak filtration performance, store in a well-ventilated, dry warehouse at 15°C to 30°C and Relative Humidity less than 60%. Do not stack pallets directly on top of each other without racks to prevent inner paper core deformation.
FAQ
Q: What testing equipment do you use to certify the filtration efficiency of your meltblown nonwoven fabric?
A: We test every single production lot using the TSI 8130A Automated Filter Tester, which is the identical technology utilized by international standard laboratories (like Nelson Labs and NIOSH). This guarantees that the BFE (>=99%) and PFE (>=95% / 99%) metrics we provide match the results you will receive during official international certification.
Q: What is the shelf life of your electret-treated fabric, and does the static charge decay over time?
A: When using our advanced Hydro-charging electret treatment, the electrostatically injected charge is embedded deep within the polypropylene matrix. Under appropriate storage conditions (a dry, cool warehouse below 30°C and away from direct UV exposure), the filtration efficiency remains stable for 3 to 5 years without significant decay.
Q: Can your meltblown fabric achieve N95 and FFP2 standards while maintaining a low pressure drop?
A: Yes, absolutely. This is our core technical advantage. By precisely controlling the melt index and air attenuation, we achieve a high fiber density of 1–5 um. This allows us to manufacture FFP2 and N95 grade meltblown fabrics that pass filtration benchmarks easily while maintaining an exceptionally low pressure drop (<=30–45 Pa at standard flow testing), preventing a stuffy breathing feeling in final respirators.
Q: Do you offer free sample rolls for laboratory evaluation and trial conversion runs?
A: Yes. We understand that medical and industrial converters must pre-test materials on their production machinery. We can provide standard sample rolls (e.g., 175mm / 260mm width) for your internal lab evaluation and machinery adaptation testing. Please contact our technical sales team to request your sample roll.
