How can you tell if a bag is non-woven polypropylene?

It’s easy to tell if a laminated bag you have is made from woven or non-woven PP. Just look inside. If it has the checker-board look of weaving, like threads going at ninety degree angles, it is woven. If it has a steady textured look, it is non-woven.
