You've got to get these to go along with your laminator! I have them in multiple sizes for different types of projects, including things for my children and for me.
 
Scotch Thermal Laminating Pouches are ultra-clear pouches that protect and add professionalism to documents you use frequently. These laminating pouches allow important information to show through with a clear, photo-safe finish making it marker-proof, spill-proof, and tear-proof.  Use laminate pouches for laminating artwork, signs, flyers, schedules, certificates, to-do lists, and other frequently used documents.
 
Most household cleaners are safe to use on the pouches, so you can disinfect them.
 
One package contains letter-size pouches that fit items up to 8.9 in. x 11.4 in. Each pack contains 200 pouches. For the best results, use these laminating pouches with Scotch Thermal Laminators. (1) Do not sanitize pouches before the lamination. Test a small amount in a corner before use, especially on important documents. Do not use acetone.
