Precise slitting and special packaging of odor free pure polypropylene are required to meet the specific demands of the face mask industry to capitalize on the excellent filtration and low-pressure drop of non-woven fibers by Monadnock.
Narrow slit widths down to 6 inch and basis weights in the 0.5 to 1 opsy range are used to offer blood resistance and excellent breathability.
Monadnock media is widely used in three-ply face mask construction. There are several common grades which are incorporated in a mask to meet the FDA defined BFE95, BFE98 and BFE99 efficiency.
The video shows the Monadnock melt blown filtration layer in the middle sandwiched between two outer layers that are typically a spun bond that adds strength and allows the mask to be folded to shape. Monadnock Non-Woven rolls are slit to width typically 175mm and can be supplied in rolls up to 40” diameter.
Monadnock Face Mask media is made with Green-e certified renewable wind powered electricity.
Like all Monadnock polypropylene media, this product is recyclable.
