Iron wire nose bridge strips are divided into single core and double core. They are composed of polyolefin polymer PP and galvanized filaments. They are on galvanized filaments with a diameter of 0.45mm-0.5mm. Coated with a layer of polyolefin polymer material.
Most domestic factories use this type, with high production capacity. The manufacturing principle is actually very similar to wire and cable processing.
Plastic nose bridge strips are also called all-plastic nose bridge strips. They are all made of polyolefin resin. Like metal wires, they bend and deform with the action of external forces. They lose the effect of external forces without rebounding and maintain their existing shape. It has constant excellent performance and can be closely integrated with non-woven materials.
Aluminum nose bridge strip, also called hot melt glue nose bridge strip, is stamped from metal aluminum plate. The advantage of aluminum is that it has good bending effect and strong shapeability. There is hot melt adhesive on the back, which can quickly bond with the mask and improve production efficiency. Smooth surface, no burrs, smooth elliptical corners. With stamping processing, large quantities can be produced quickly, and product quality is guaranteed! Safe and environmentally friendly! Meet export standards! Mainly used for N95, kN95 masks.
