Natural, these are made with die-cut cellulosic film, which is then cut/formed/inserted into a form/fill/seal pouch, then liquid formula injected into pouch, then pouch sealed. Voila - facemask. Our firm (we are the pouch kings of the New World) has looked into it, given our equipment and skill-set, but the die-cutting equipment and retro-fitting needed to fit our nonwoven wipe insert line is expensive. Unless someone approaches us with a solid order in the millions of mask units, it will remain on the drawing board for now. Try Taiwan in the meanwhile.
