This is brand new SMS surgical wrap that is H600 weight and comes in 36 x 36 pieces with dual layers, one green and one blue.
For those making masks this is enough material to make 50 pleated masks - 25 green and 25 blue.
We also sell the elastic material to make the straps as well as meltblown. SMS surgical wrap actually comes with a meltblown layer. SMS = spun/meltblown/spun. The inner meltblown is not has thick as in a 3ply mask but offers good filtration and a water proof barrier.
Here is an example design where this material could be substituted
