Lamination is a process that involves covering a material, like paper or cardboard, with a thin layer of plastic. This protective layer helps to keep the material safe from damage, such as tears, spills, or fading. Many people use lamination for important documents, like certificates or ID cards, to ensure they last longer and look professional. The lamination process can be done using a machine that applies heat and pressure to seal the plastic around the material. This technique is popular in schools and offices, where items like posters and menus are often laminated to maintain their quality and appearance over time.
