Substrate-polyurethane paper?

[chas*e]

I was buying meat at the wholesalers and while I was at the counter I seen that he was using a big roll of meat wrap paper to cover the meat. You know that brown paper with wax on one side. It comes in a 12" inches thick roll and is 24in or 18" inches wide. I asked how much it was for the 18 in roll and it was only $15. I found out that the surface is covered with polyurathane on one side. That is the side that touches the meat(the inside). I thought that it would be great substrate rather than newspaper for my enclosures. I would imagine that it would be OK since the Food and Drug government passed it for human use(guidelines are better for humans than animals..lol) Anyways for the past week I have been using the Poly paper and, I tell ya, the cleanup is sooo easy because with the poly side up, it is waterpoof(poo-proof)...I was just wondering if anyone else has ever used this stuff with any ill effects.??? PS...it looks cool too because it is brown rather than the days top headlines as the newspaper(with the newspaper as substrate I put the politician's faces up)
