Shrinkfast 998, Operatin

due to it already having been pulled taut
through shrinkage of the four sides.
f. The pallet is now ready for shipment. Lift
truck forks may be driven through the film
where it covers the wooden pallet; the punc-
tures will not propagate.
NOTES:
The most important fact to keep in mind is
that heat only softens the film. The greatest
amount of shrinking occurs as the film
cools. It is a common fault of the inexperi-
enced operator to apply too much heat to
the film often concentrating the heat and
waiting for the film to shrink before moving
the gun.
Keep the gun moving.
With a little practice, you will find you can
hold the gun closer to the film and sweep
faster often shrinking a pallet in less than 2
minutes.
It is absolutely necessary that the four cor-
ners of the bag be caught under the pallet.

If this is not done, the effectiveness of
shrink palletizing is considerably reduced.
2. Patching
Occasionally, holes will appear in the film.
These may be easily patched by laying a
square of film over the hole and applying
heat around the edges welding the patch to
the bag. The same technique may be
applied to reinforce edges or corners with
patches.
3. Shrink Wrapping Large Or Odd
Shaped Loads
Shrink wrapping is a versatile method which
may be employed in a great variety of appli-
cations. For example, shrink wrappers rou-
tinely wrap irregular objects such as canoes
using sheets of shrink film.
Objects which are too big to fit under a bag
may be wrapped by using several sheets of
shrink film joined together if the following
two precautions are observed:
