Actually, what I use is freezer paper.

I've been using the Reynolds brand of freezer paper for many years, because that's what is normally sold in local Montana stores. When used to tightly double-wrap meat, it's kept the meat of various packages free of freezer burn for 3-4 years.

Thanks for all the information, guys. I found out what I wanted to know, and am now going to bow out of this thread.
