Special 500 pouches per bag packaging includes at least 5 silicone coated laminating "carriers" .

TIPS: Industry standard specification for 7 mil laminating pouches is 7 mils on each flap for a total of 14 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 authentic Oregon Lamination trademarked laminating pouches bearing our purple and white label. Choose the best value laminating pouches available.
