Excellent for liquid and gas filtration, UltraFlo is a trilaminate composite that incorporates spunbond outer layers sandwiching an inner layer of meltblown micro fibers. The outer layers provide strength and stability, while the inner layer gives UltraFlo its exceptional filtering properties. Composed of polypropylene, UltraFlo's outer layers provide good edge stability with minimal tendency to fray or unravel after slitting or die cutting, and its multi-layer construction gives UltraFlo excellent uniformity.

• Continuous filament construction to minimize fiber migration and add strength
• Polypropylene
• Custom multi-lamination constructions can be developed
• Thermally and ultrasonically sealable
• Product weights: 0.45-2.6 osy (15-88 gsm)
