A thermal laminator is a device used to protect and enhance documents by applying a layer of plastic film over them. This process involves heat, which melts the adhesive on the film, allowing it to bond securely to the paper. Thermal laminators are commonly used in offices, schools, and homes to preserve important documents, photos, and artwork. These machines come in various sizes and can laminate items ranging from small ID cards to large posters. Users typically place the document in a laminating pouch, feed it into the machine, and wait for it to finish. Popular brands include Fellowes and Scotch.
