I still don't like that middle layer

Since this project started, there have been many others turning Polypropylene masks into things via injection or extruder molds  (e.g. this bench). And they generally just toss the whole mask in. I think this is fine in bulk quantities, but if you are making thin sheets like us, that mysterious middle layer seems to make them much more fragile. so watch out!
