TruLam 5 Mil Credit Card 2-1/8 in. x 3-3/8 in. Laminating Pouches are the exact size of a standard issue credit card with no trimming required. The finished size slides easily in and out of a wallet - great for pocket schedules, identification, and more! These pouches are sealed along the long edge, making it easy to line up your insert. Please remember that you need a 1/8 in. border all the way around your insert to ensure a proper air/watertight seal to prevent the laminate from splitting. TruLam thermal laminating pouches are compatible with all popular laminating machine models, including laminators from TruLam, Akiles, Sircle, Tamerica, Banner, Purple Cows, GBC, Fellowes, and Scotch. These laminating sheets are made of high quality, high clarity laminating film and premium adhesive resins for crystal clear laminated documents. To use, simply center your document inside of the laminating pouch and insert it into a pre-heated pouch laminator (following the manufacturer's instructions for setting the machine based on the thickness of the pouch).
