The 3M Cold Laminators use a laminating cartridge or roll laminating that easily inserts into the laminator. No heat or electricty is required. The process offers a cold laminate which is excellent for thermal/heat sensitive material. The cold lamination is pressure-sensitive. When the item being laminated comes in contact with the sticky side of the laminate/substrate it will adhere to the item. These cold laminators use a continuous laminating film great for banners or long projects.
