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 like folders.
