20-60 GSM Meltblown Nonwoven Filter Media for Vacuum Cleaner Dust Bags High Dust-Holding Capacity & Low Airflow Resistance
Product Overview
Engineered specifically for vacuum cleaner dust bags and industrial dust collection systems, our 20 – 60 GSM Meltblown Nonwoven Filter Media is produced from 100% virgin polypropylene (PP) using high-velocity hot-air fiber attenuation. Featuring an ultra-fine fiber network with gradient pore structure, it delivers high fine-dust capture efficiency, superior dust-holding capacity, and low pressure drop—preventing suction loss and premature bag clogging.
Key Performance Advantages
High Dust-Holding Capacity, Prevents Early Clogging: Unlike standard mask-grade meltblown that clogs quickly under heavy dust loads, our dust-bag grade features an optimized fiber web structure that traps fine particles deep within the media, extending bag service life.
Balanced Efficiency & Low Airflow Resistance: Maintains high interception of fine dust, pollen, and wood/cement particles while keeping pressure drop low—protecting vacuum motors and maintaining strong suction power.
100% Virgin PP, Ideal for Spunbond Lamination & Ultrasonic Welding: Pure polypropylene composition offers clean thermal bonding and ultrasonic weldability with PP spunbond support layers (for SMS / SMMS multi-layer dust bag composites) with zero odor or filler impurities.
Precision Slitting & Consistent Roll Quality: Available up to 1,600 mm max width with custom narrow-width slitting, uniform tension, and minimal splices for high-speed automatic bag-making lines.
