A laminator is a machine that protects and enhances documents by covering them with a thin layer of plastic. This process, known as lamination, helps to keep papers safe from spills, tears, and fading. Laminators are commonly used in schools, offices, and homes to preserve important documents like certificates, photos, and menus. There are two main types of laminators: hot laminators and cold laminators. Hot laminators use heat to seal the plastic around the document, while cold laminators use adhesive to stick the plastic without heat. Both types are easy to use and can help keep your important papers looking new for a long time.
