TIPS: Industry standard specification for 10 mil laminating pouches is 10 mils on each flap for a total of 20 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. Insist on the authentic Trademarked product this listing is for bearing our purple and white label.
