LAMINATION process can be defined as the process in which one side or both sides of the item,are coated by a film.The coating film and the material to be coated are brought into contact with each other with the help of the roller.A permanent bond is formed between the materials by the application of heat or pressure or both.The heating process in lamination is most critical and it is done either at the roller assembly or before the roller assembly.The single integrated material produced after the lamination is called as laminate.Hence a laminate can be a combination of clearly different plastic film materials or plastic with materials like paper,aluminium foil,cellophane etc.
