The general body mask can be divided into three layers: inner, middle and outer. The inner layer is ordinary. Hygienic gauze or non-woven fabric, the middle layer is generally made of super-new polypropylene fiber meltblown material, but the outer layer is also made of non-woven fabric or ultra-thin polypropylene meltblown material layer.
