Quality meets or exceeds all major brands, but at generic pricing.

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.
