Maximum card size recommended for this pouch is 2-1/4" x 3-5/8" (or less) to leave a standard 1/8" border of clear laminate around card for a secure sealed edge. TIPS: Industry standard specification for 5 mil laminating pouches is 5 mils on each flap for a total of 10 mils added to your paper sheet. Also, 1 mil equals 1/1000th of an inch (or 25 microns metric). The industry calls these laminating pouches when they are sealed on only one edge instead of three. They should be called laminating folders. Note: All laminating pouches are NOT the same, especially in clarity and bonding.
