The mask has three layers, (inner layer) moisture absorption layer, (middle layer) core filter layer, and (outer layer) water blocking layer.
S layer: Polypropylene special resin (Sinopec) -Nonwoven Fabric Factory-Mask Factory

Layer M: Polypropylene special resin with high melt index (Sinopec)-Modified plastics factory (during epidemic prevention, Sinopec researched and produced special materials for meltblown fabrics)-Meltblown nonwoven fabric factory-mask factory.

Meltblown cloth, commonly known as the “heart” of the mask, is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs. Meltblown cloth is a film made of polypropylene with high melt index. It is a film composed of many crisscross fibers stacked in random directions. The fiber diameter ranges from 0.5 to 10 microns, and the fiber diameter is about 30 cents of the hair thread. one.

Application: Meltblown
