I really don't know I bought a few rolls that where 8' wide by 30' long from my inlaws neighbor. He used them like drop clothes or something while sand blasting. Kind of like billboard vinyl material. vinyl with a woven layer in between layer. You can cut a slit with a knife but yet cant rip it...
Finally got some stag pens emptied out so I could recover enough of them to use for single matting brood pens..
just thought i would share a couple pen pics
