A laminate is a material that can be constructed by uniting
two or more layers of material together. The process of creating a
laminate is lamination, which in common parlance refers to the
placing of something between layers of plastic and gluing 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.
There are different lamination processes, depending on the type of
materials to be laminated. The materials used in laminates can be the
same or different, depending on the processes and the object to be
laminated. 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. Another reason to laminate wooden strips into beams is quality
control, as with this method each and every strip can be inspected
before it becomes part of a highly stressed component such as an
aircraft undercarriage.
Examples of laminate materials include Formica and plywood.
Formica, which refers to a specific brand name of materials by its
manufacturer with the same name, and similar plastic laminates are used
in the production of decorative laminates, using either a high or low
pressure thermo-processing system. Decorative laminates (such as Maica Laminates,
Wilsonart or Laminart) are produced with kraft papers and decorative
papers with a layer of overlay on top of the decorative paper, set
before pressing them with thermoprocessing into high-pressure decorative
laminates. A new type of HPDL is produced using real wood veneer or multilaminar veneer
as top surface. Alpikord produced by Alpi spa and Veneer-Art, produced
by Lamin-Art are examples of these types of laminate. High-pressure
laminates consists of laminates "molded and cured at pressures not lower
than 1,000 lb per sq in. (70 kg per sq cm) and more commonly in the
range of 1,200 to 2,000 lb per sq in. (84 to 140 kg per sq cm).
Meanwhile, low Pressure laminate is defined as "a plastic laminate
molded and cured at pressures in general of 400 pounds per square inch
(approximately 27 atmospheres or 2.8 x 106 pascals).
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. Boxes and other containers are also laminated using a UV coating.
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.
Further, laminates can be used to add properties to a surface,
usually printed paper, that would not have them otherwise. Sheets of vinyl impregnated with ferro-magnetic
material can allow portable printed images to bond to magnets, such as
for a custom bulletin board or a visual presentation. Specially surfaced
plastic sheets can be laminated over a printed image to allow them to
be safely written upon, such as with dry erase markers or chalk. Multiple translucent printed images may be laminated in layers to achieve certain visual effects or to hold holographic
images. Many printing businesses that do commercial lamination keep a
variety of laminates on hand, as the process for bonding many types is
generally similar when working with arbitrarily thin material.
Invention
Lamination was invented by Dr. Morris M. Blum, DDS, a dentist in
1938. Although it may sound surprising, it turns out that dental
laminate was the inspiration for the first lamination of a photograph.
Dr. Blum used clear resin that was normally used for capping and bonding
teeth to laminate a photograph of his wife. He is recognized to this
date for his contributions with a special scholarship fund at the
University of Minnesota.
Types of laminators
Three types of laminators are used most often in digital imaging:
- Pouch laminators
- Heated roll laminators
- Cold roll laminators
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 laminate
