XM2500 refills come in several different configurations, including adhesive applications as well as one or two-sided lamination. These films are 25" wide and are compatible with the XyronPRO XM2500 cold laminator. All refill types are acid-free, which means they will protect your items without degrading them. This Xyron lamination film offers a consistent and clear finish on a variety of materials, including heat-sensitive ones, and is applied with nothing but strong, pressure rollers. This means no mess and no smell; just clear, smooth lamination.
