A cold laminator is a device used to protect and enhance documents, photos, and other materials without the need for heat. It applies a layer of plastic film over the surface, sealing it to prevent damage from moisture, dirt, and wear. This process is ideal for preserving important items like certificates, menus, and artwork, ensuring they last longer and look professional. Unlike hot laminators, which use heat to bond the film, cold laminators use pressure to adhere the film to the material. This makes them safer for heat-sensitive items, such as certain types of paper and photographs, which can warp or melt under high temperatures.
