These Xyron® XM1255 refill cartridges are compatible with the XyronPRO XM1255 cold laminator. They come in a variety of styles, including adhesive only applications, one-sided laminate and two-sided laminate. They are all pressure-sensitive, so do not use any heat with the XM1255; instead, they are applied to your items with strong, even pressure. This pressure means there is no mess or smell while you laminate, and makes it safe to use with heat-sensitive materials. All XM1255 cartridges are acid-free, so they will protect your items without degrading them. Refill your supply, or try a new application when you buy XyronPRO XM1255 laminator refills online today.
