Along that line of thought, one thing I tried about a year or so ago was heat shrink plastic like you find wrapping music or video CD's.
I bought some from ULine for relatively cheap and more than I could ever use. I heat sealed the board and mask inside of the pouch and ran the whole thing through my laminator. to shrink the plastic wrap.
The biggest problem I had was that the corners would not shrink evenly and was somewhat wrinkled. However in the center the mask was held quite tightly to the board. I have not done anymore testing since then, but that would be an option if someone wanted to try a vacuum-less method.
