The medical mask is made of three-layer cloth and aluminum nose wire. The inner layer is a common non-woven fabric, used to absorb the moisture released by the wearer;the outer layer is a waterproof non-woven fabric, used to isolate the external polluted air; the middle filter layer is a medical melt-blown cloth for blocking bacteria.
Due to the protrusion of the nose, no matter whether the face masks is thick or thin, it can’t fit the face completely without the aluminum nose strip. The aluminum strip needs to be bent and deformed with the action of external force and has no rebounding without loss of external force, maintain the existing shape.
When purchasing aluminum nose wire, you had better choose those with hot melt adhesive on the back, which will be convenient further processing. Some choose to produce aluminum nose wire by themselves. Haomei Aluminum offers you quality aluminum strip for face mask.
