We have a wide variety of sizes and thickness when it comes to laminating pouches--and here lie the 7 mil pouches! This thickness of films gives a much more sturdiness and protection (compared to 5mil) in addition to providing handling and UV protection. Its biggest draw is its sturdiness--these don't bend or fold easily. It can withstand weather and frequent handling, perfect for menus and ID cards. So if you need more rigid protection, then 7mil pouches are perfect for you! We have lots of sizes and colors to choose from--ask our representatives if you have any questions!
