3 Inch Core Thermal Laminating Film Rolls are wound on a cardboard tube that is 3 inches in diameter. The core slides over the mandrel of your roll laminator and is threaded through the laminator. If unsure, check the owner's manual of your roll laminator for the proper core size used with your laminator.
Laminating film comes in 1.5, 3, 5, 7 or 10 mil thickness. The thicker the laminating film the more rigid the result. A 1.5 Mil film will protect your document while keeping it very flexible. 3 Mil film will add slightly more body while still being pretty flexible, 5 Mil will add yet more body, 7 Mil will be more rigid with some flexibility and 10 Mil film will be quite rigid.
