Plywood layer, fiberglass?

[ctopher]

I recently purchased some prefinished 3/4" plywood to make cabinets.
On some cuts I noticed what looks like strands of fiberglass sticking out?
Is this something new manufacture's are doing?
Attached is one example.

Not that I've heard of - though the stuff I spec isn't the sort of stuff you'd use in a cabinet. So maybe for some of the prefinished stuff?
