A laminate is a material that is constructed by uniting two or more layers of material together. The process of creating a laminate is lamination, which generally refers to placing something between layers of plastic and bonding them with heat and/or pressure, usually with an adhesive. The materials used in laminates can be the same or different. An example of lamination using different materials would be the application of a layer of plastic film — the “laminate” — on either side of a sheet of glass — the laminated subject. Vehicle windshields are commonly made by laminating a tough plastic film between two layers of glass.
