10.1.2.8.Lamination
Laminations are combination of various plies which gives material unique properties that are not given by a single material alone. In lamination process, adhesives are used. One plastic material is coated with an adhesive and subsequently adhered to another material. Laminates can be prepared by using only plastic films or plastic to paper, or aluminium foil to plastic or metalized plastic. For water based solvent based and solvent less laminating process, polyolefin films are surface treated on the laminating side although wet or molten adhesive is applied during lamination process.
