I have a brother who has more than a passing acquaintance with the manufacturing processes used to make burger pods, disposable cups and the like.
I pointed out that one of the Big Three auto makers bragged about making 2000 N-95 masks in their first shift of production.
My brother didn't quite smirk.
I asked him what a typical plant that makes "killing the planet" disposable burger pods makes in a shift. He said "Anywhere between 2 million and 6 million units. They often run three shifts a day so call it 6m to 18m units a day."
Granted, paper and EPS cups are not spun-bonded poly-pro but conceivably some of the same technologies could be used. That is, heat stamping, di-electric bonding and the like. The transfer equipment would have to be adapted and elastic hand-stapled but that is immensely faster than sewing.
Point being, if everybody who provides medical care is supposed to change PPE between patients then 2000 masks will disappear in a heartbeat. 18 million units in a day, though, that gets peoples attention.
