The 27C laminator runs poly-in and poly-out
pressure sensitive adhesive (PSA) films. Poly-in
means the adhesive side of the film is on the inside
of the web. Poly-out means the adhesive is on the
outside of the web.
The machine can perform three functions:
Decaling (laminating and applying an adhesive
to the back of the item).
Mounting, using one film.
Mounting, using no film.

IMPORTANT: The top and bottom rolls of laminating
film must be the same width.
Always change the top and bottom supply rolls at
the same time. Near the end of each roll of most
laminating film is a label stating,
Warning – End
of Roll. The appearance of this label on either the
top or bottom roll requires that new rolls of film
be installed as soon as the item presently being
laminated completely exits the rear of the laminator.
Do not introduce any additional items into the
laminator when the warning label is visible.
Adhesive will deposit on the rollers if:
One or both rolls of film are allowed to run
completely off its core.
Only one roll is used.
Different widths of rolls are loaded together.
Either roll is loaded with the adhesive side
against a roller.
There are two methods of loading film.
Using a threading card.
Tacking new film to existing film.
Prior to loading film, the safety shield and feed table
need to be removed.
