Extensive Definition

A laminate is a material constructed by uniting two or more layers of material together. The process of creating a laminate is lamination, which in common parlance refers to sandwiching something between layers of plastic and sealing them with heat and/or pressure, usually with an adhesive. However, in electrical engineering, lamination is a construction technique used to reduce unwanted heating effects due to eddy currents in components, such as the magnetic cores of transformers.
The materials used in laminates can be the same or different. An example of the type of laminate 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. Plywood is a common example of a laminate using the same material in each layer. Glued and laminated dimensioned timber is used in the construction industry to make wooden beams, Glulam, with sizes larger and stronger than can be obtained from single pieces of wood.
Examples of laminate materials include Formica and plywood. Formica and similar plastic laminates (such as Pionite, Wilsonart or Centuryply Mica are often referred to as High Pressure Decorative Laminate (HPDL) as they are created with heat and pressure of more than 5 lbf/in² (34 kPa). A new type of HPDL is produced using real wood veneer or multilaminar veneer as top surface. Alpikord is one of these laminates produced by Alpi spa.
Laminating paper, such as photographs, can prevent it from becoming creased, sun damaged, wrinkled, stained, smudged, abraded and/or marked by grease, fingerprints and environmental concerns. Photo identification cards and credit cards are almost always laminated with plastic film. Lamination is also used in sculpture using wood or resin. An example of an artist who used lamination in his work is the American, Floyd Shaman.

Types of laminators

Three types of laminators are used most often in digital imaging:

Film types

Laminate film is generally categorized into these five categories:
  • Standard thermal laminating films
  • Low-temperature thermal laminating films
  • Heatset (or heat-assisted) laminating films
  • Pressure-sensitive films
  • Liquid laminates
