IMPORTANT: Don’t laminate one-of-a-kind documents unless you are sure of your
laminating skills and can afford to damage or ruin the document. Don’t laminate
valuable items such as stamps, baseball cards, autographs or other collectibles
because the value of such items can be destroyed by lamination. Collectors generally
value these kinds of items only in their original state.
Remember that you cannot laminate thermal paper, such as typical fax paper, because
it is activated by heat and will turn black. Also, remove paper clips and staples because
they can damage the rubber rollers. Be careful about laminating anything that will be
affected by heat. For example, the colors in crayon drawings may run together or be
smeared, especially if the crayon layer is heavy. Light crayon drawings may not be
affected, but test an expendable sample of any item that may not laminate well.
IMPORTANT: Éviter de plastifier du papier thermosensible, comme le papier de
télécopieur, pusqu’ll noircira sous l’effet de la chaleur, et enlever les trombones et les
agrafes gul risquent d’endommager les rouleaux de caoutchouc. Prendre certaines
précautions avant de plastifier des articles susceptibles de réagir à la chaleur comme
les dessins au pastel dont les couleurs baver et se mélanger, surtout si la couche de
pastel est épaisse. Les pastels en couche mince peuvent ne pas réagir, mais, en cas
de doute, il est préférable de faire un essai avec un échantillon perdu.
Ne pas plastifier les documents importants dont il n’existe qu’un seul exemplaire, à
moins de bien malitriser la technique de plastification. Ne pas plastifier non plus les
articles de collection comme les trimbres, les cartes de baseball, les autographes ou
autres, qui peuvent perdre leur valeur pour les collectionneurs s’ils ne sont plus dans
leur état d’origine.
IMPORTANTE: Recuerde que no puede laminar papel térmico, tal como el papel de
fax tipico, ya que es activado por el calor y se tornará negro. Retire también cualquier
sujeta-papeles o grapa, puesto que pueden danar los rodillos de goma. Evite laminar
cosas sensibles al calor, por ejemplo, los colores de dibujos hechos en lápiz de pastel
pueden no ser afectados, pero ensaye con alguna muestra descartable, en los ìtemes
que podrían no laminarse bien.
No lamine ningún documento único, a no ser que esté muy seguro de sus habilidades
de laminador y pueda permitirse arruinar el documento.No lamine artículos de valor,
como estampillas, tarjetas de béisbol, autógrafos, u otros coleccionables, ya que su
valor puede ser destruido por la laminación. En general, las coleccionistas valoran
este tipo de artículo en su estado original.

1-2 FEATURES & BENEFITS
Your new laminator has several standard features that set it apart from other models.
• Intelligent heat controllers simultaneously display both the set temperature and
the actual temperature. The microprocessor-based control quickly learns to
anticipate the heat demand of each job and keeps the actual temperature within a
few degrees of the set temperature.
• Laminating and pull rollers are covered with quality silicone rubber for superior
release, higher lamination quality and easier cleaning. The laminating rollers and
pull rollers are interchangeable.
• Removable heat shoes are teflon coated to reduce film abrasion. They can easily
be unplugged and taken off to facilitate cleaning or replacing the laminating rollers.
Built-in retractable slitters save an enormous amount of cutting time by trimming
away side scrap during the lamination process. The two heads can be adjusted
independently with great precision, even while the laminator is running.
• Forced air cooling is essential when running thicker films, because the lamination
needs to be cooled to get good results.
• Easy access controls are conveniently located and grouped for effective operation.
• The safety guard is built into the feed tray to make sure it will always be in place
when laminating.
• The precision feed tray has moveable left and right side quides and can be
replaced with the optional Power Feed Tray in seconds.
• Laminating and pull rollers are covered with quality silicone rubber for superior
release, higher lamination quality and easier cleaning. The laminating rollers and
pull rollers are interchangeable.
• Very strong steel cores. These prevent roller flexing and insure uniform pressure
across the width of the laminate, giving you the best quality lamination available in a
medium-duty commercial machine.
• Controls to open and close the laminating rollers. The controls make threading
easier and allow even heating of laminating rollers during warm-up.
• 100% Made in the U.S.A.

1-3 OPTIONS
• Power Feed Tray is designed exclusively for the HD-25, this power feed tray has
received good reviews for its easy setup and accuracy. Autofeeding is the first step
toward automated lines and lower production costs. A separate specification sheet
is available.
• 2 ¼-inch supply roll mandrels are available at no additional charge at time of
purchase in place of the standard 3-inch mandrels.
• Risers lift a machine off its work surface, allowing longer supply roll brackets
(extensions) to handle larger diameter rolls of film. Risers are not needed with a
stand.
• Stand An extruded aluminum stand is designed to place the unit at optimum
feeding height and to provide a secure base. Casters are available for either stand,
but it is suggested they be removed for stability and safety once the machine is in a
permanent location.
• Upper fan assembly. When running thicker films, additional cooling capacity
enables work to be run at a higher speed.
• Scrap rewind. Enables cold lamination by removing the release liner material from
pressure sensitive adhesives, film and vinyls.
• Footage counter. For accurate measurement of film usage.
• Additional slitter heads. For multiple-up trimming.

1-5 PRINCIPLES OF OPERATION
The HD-25 “Workhorse” laminators operate by pulling film with a thermally activated
adhesive over a heat source and into a set of laminating rollers. Film from the supply
rolls passes over heat shoes to activate a polyethylene adhesive layer on the film. It
then passes through rubber rollers to apply pressure and bond the film to the item being
laminated. The adhesive is pressed into the ink and fibers on the surface of the paper.
The strength of the lamination bond can be checked by cutting a large “X” on the
surface of a laminated sample with a sharp blade. Use the tip of the blade to pry up one
corner of the “X”. Grab that corner and pull up the film. Ink and/or paper fibers coming
up with the layer of film indicates a good adhesive bond.
If the film comes up too easily, with no ink or paper, the lamination was probably done at
too low a temperature. Check the instructions that may have come with your laminating
film and/or the lamination temperature chart in section 5-5.
Please note that when doing an X-test on glossy (coated) paper, a good X-test will pull
up ink only. The film should not come up easily. When laminating material that is not
glossy (uncoated), the paper is often more fibrous and a good X-test will yield ink and
paper fibers coming up with the film.

1-6 LAMINATING FILM
Most thermal laminating film consists of two layers: a base of polyester and an adhesive
layer of polyethylene. The polyester layer forms the harder outer surface of the film and
does not melt at laminating temperature. It provides rigidity and protection for your
laminated items. The greater the polyester content, the higher the level of protection,
rigidity and luster. The polyethylene layer melts at laminating temperature and bonds
the film onto the subject material under the pressure of the laminating rollers. As an Xtest demonstrates, the adhesive is pressed into the paper and fills irregularities in the
surface.
The proportion of polyester and polyethylene in a film is usually described with
numbers. For example, a “1-2” film consists of one mil of polyester and two mils of
polyethylene. The first number refers to the base layer. The second number refers to
the adhesive layer. A mil is 1/1000 of an inch.
Since polyester is the more costly of the two types of plastic generally used in
laminating film, a “3-2” film will cost more than a “2-3” film. Both are 5-mil films but the
“3-2” version will seem a little thicker on a piece of laminated material because it will be
slightly stiffer. Thermal laminating films are available in many different base/adhesive
combinations. Five mil film, for example, can be found in 1-4, 2-3, 3-2 and 4-1
combinations.
In the US laminating trade, the generally accepted practice is to describe two-sided
lamination, or encapsulation, by the thickness of one layer of film. For example, “3-mil
lamination” should refer to lamination with two layers of 3-mil film. If you are buying or
selling laminating film or lamination services, please make sure both parties understand
the film descriptions being used. There is a huge variety of thermal laminating films
available to suit many different kinds of application. Here are some of the more
commonly used “special” film types or film additives:
• film with low-melt adhesives, also known as co-polymer films; these often have
better clarity and are less likely to curl or ripple
• matte films to eliminate glare or to accept printing or writing; many suppliers offer
films with both glossy and matte finishes
• film with UV inhibitors to protect colors in the laminated material from fading in
sunlight
• thermal film that has a pressure-sensitive adhesive and a release liner on its outer
side; for example, a poster with this material laminated on the back could easily be
mounted without fasteners or tape
• “liner films” with a protective liner on the top outer surface...after a piece of material
has been laminated, trimmed, packed, and shipped, the person using the material
10
can remove the protective liner revealing a surface perfectly free of dust, scratches
or abrasion
• opaque or colored films for the back side of a lamination; these can form a border for
a laminated piece
• iridescent clear films for special visual effects
• permanently waterproof films for outdoor, underwater, or special applications; the
most common thermal laminating films are made with water-based primers and will
eventually de-laminate if continually exposed to water or weather; truly waterproof
films are made with special primers
Rolls of film may be purchased in different widths. The size of the laminator is the only
limitation to the width of the film rolls you can use. Make sure the upper and lower roll
widths are the same, and are aligned with each other.
When installing film, always center the rolls of film on the supply roll mandrels. Because
it does not hold heat well, 1.5 mil film can be the most difficult gauge of film to use. A
standard 1.5 mil film will run at about 310 °F, while a 3 mil film with the same adhesive
type will run at 280 °F. Even when applied at 310 °F, the 1.5 mil film will not adhere as
consistently as the 3 mil film applied at 280°F, or a 5 mil applied at 250°F. For many
applications, 5 mil film does a much better job of protecting and enhancing items.
Ten mil film is suggested for those applications that need the most protection and
rigidity. Seven mil films are also available.
Rolls of film are sometimes spliced. Most film suppliers will mark a splice with colored
tape. This way, you can see the splice as a “dash” of color on either end of the roll. If
you spot a spliced roll in advance, you can put it on the top supply roll mandrel in order
to see the splice coming more easily and avoid putting material under the splice. Or
you could put it on the bottom roll if you plan to be laminating items that will never be
seen from the backside.
