Lamination machines are devices used to apply a protective layer of plastic film over documents, photographs, or other materials. This process enhances durability, water resistance, and visual appeal. Lamination can be done through heat or cold methods, with heat laminators using heat to bond the film to the material, while cold laminators apply adhesive films without heat. These machines are commonly used in offices, schools, and print shops to preserve important documents, create professional presentations, and enhance the longevity of printed materials.
