Film Unwinder
Product Tray
The product tray is the adjustable metal platform used to separate the film and to
facilitate insertion of the product between the bottom and top layers of film.
The product tray is adjustable to achieve proper depth equal to the total width of the
package, thereby allowing the product to be placed precisely at the center-fold of the
film each time.
Film Support Rollers
The film support rollers are positioned at the front end to cradle the film roll as film is
dispensed. Vertical rods, one at each end of the film roll, help keep the film aligned with
the product tray.
Pin Perforator
The pin perforator is located at the exit of the film unwind. It creates holes in the film (to
allow air to escape during shrinking). The pin perforator allows some adjustment and
must be properly located with relation to the depth of packages to be sealed. The
position of the pin perforator should always be reviewed when changing the machine for
a different size package or different film size. It is adjusted by the adjustment knob at
the top of the film unwind and located to avoid dropping or damaging and so it is
mounted out of the way.
Mounting Film
Select the proper width of center-fold film for the product being packaged, taking into
account the width and height of the package. With the package properly positioned
within the film in the sealing area, allow sufficient film to overlap the sealing bars so that
a seal can easily be made without possibility of openings due to insufficient film
coverage.
Place the film roll on the support rollers so they cradle the film. (See the illustration on
the following page.) Place the center-fold away from the operator, to the back of the
machine. Position the film roll on the rollers and tighten the bolts on the film rack collars
to hold the film roll in position.
Decide whether the film is an A or B wind, and then thread it straight across and through
the pin perforator. (See the following illustration.) When threading the film, make sure to
pull excess film across the product tray and into the sealing area to ensure sufficient film
to begin. When you have threaded the film, separate the top film from the bottom and
insert the product tray between the film top and bottom. Make sure that the center-fold
of the film is at the back of the product tray. This allows the operator to insert product on
the product tray between the top and bottom layers of film to prepare to move the
