A laminating machine is a device that covers a document or other material with a protective layer on both sides. Usually, this layer is a plastic film, which is heat-bonded to the material and confers increased strength, durability and longevity to it.
Laminating machines are classified by their lamination processes. The five methods are liquid lamination, low-temperature lamination film, high-temperature lamination, pressure-sensitive lamination and the common thermal lamination. There are special lamination machines that magnetize materials by heat-setting vinyl with ferro-magnetic elements inside, which causes the laminated poster to attract magnets. Office laminating machines are used to protect important documents.
