I mostly use this product for my job as a pre-kindergarden instructor. I laminate mazes wipe off pages home-made games books letters and numbers for re-use and protection. I also laminate different articles to place in my "parent's corner"~ articles that deal with child development what's new health issues concerns or anything I want for the parents to read. Throughout the school year I laminate name cards for the different centers in my classroom. I can always count on trusting the laminating pouches to do their job so that the things I post will keep through the years.
This is a good product but larger than our laminating machine is meant for so we have to take it out and re-insert midway constantly and if not done well it can cause air pockets.
I'm just starting laminating. The 3 mil were a little too flimsy for my needs. I have found 5 mil cheaper but may be having problems with them being wavy. Time will tell
