Film Handling Components
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 between the lower idler rollers and is completely
synchronized with the seal arm. It creates holes in the film (to allow air to escape during
shrinking). The pin perforator is adjustable 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 size film.
It is adjusted by the adjustment knob at the bottom of the film rack. The pin perforator is
mounted inside the film rack of the machine to avoid dropping or damaging and so it is
mounted out of the way.
Film Brake
The film brake is positioned at the front end of the cradle rollers and creates a drag that
maintains tension on the film as the film is dispensed. The operator should from time to
time re-check the setting of the
film brake for proper tension. The film brake’s purpose is
to reduce overruns or slack in the film.
Mounting Film
Standard Cradle-Mount (Unpowered) Film Unwinder
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 of the cradle-mount film unwinder. (See the
illustration on the following page.) Place the center-fold away from the operator, to the
