The theory - Pressure sensitive film
Cold or Pressure Sensitive laminating involves using a self adhesive
film, usually with a release paper. This has the advantage of
being able to stick to difficult to laminate items,
such as some inkjet prints or similar
media.
Laminating with pressure sensitive film
involves removing the protective
layer of release paper from the film,
and then pressing the adhesive layers
firmly to the item being laminated. This
firmly bonds the film to the surface of the
item, resulting in lasting protection.
Most laminating done with pressure sensitive
laminates is single sided, as the cost of double
sided lamination is expensive.
Underlay paper
Underlay is the term used to describe an inexpensive paper material which feeds into the machine
below the laminated item. Its sole purpose is to prevent the adhesive on the pressure sensitive
film coming into contact with the rubber rollers during single sided laminating.
Cheap paper or plastic of most types can be used. It should be wider than the pressure sensitive
film, and not easily stretched. When the laminated item is trimmed flush to the edges, the
underlay will fall off and can be discarded.
This illustrates how a cross
section of pressure sensitive
film would appear.
