I have never done a big job with laminating, so I just buy the self laminating sheets. They also looked frosted and you pull them apart and put your paper in between and press out so no air bubbles and it works pretty well. But if you have a lot to do, it may not be the way to go. I think I get about 5 sheets of 5x7 for $1.50 uptown...
