Non-woven disposable face mask is made of two layers of non-woven fabric and one layer of filter paper. The two layers of non-woven fabric are respectively at the outside of the mask and the inner side contacting the skin. Usually, We use the medical non-woven fabric material with a weight of 20 or 25 grams per squaremeter. In the middle is a layer of filter paper for filtration and bacteria prevention. The above three layers of materials are welded by ultrasonic, forming a mask body. According to different requirements, there are generally FFP1 (80%), FFP2 (94%) and FFP3 (97%) face masks with different filtration efficiency.
There is a nose strip at the up side of face mask, made of environmental plastic. It makes the face mask be comfortable adjustment according to different face shapes. The earbands on both sides of the mask are welded by ultrasonic too, which is very firm and not easy to fall.
We have not only common flat disposable face mask, but also N90 and N95 face mask, which is thicker and better adhesion.
