LAMINATING TIPS

12.1

De-Curling

The sheet to be laminated needs to be generally flat and wrinkle free. Many items to be laminated
are supplied to you in a rolled up form, this can cause feeding difficulty if the leading edge curls up
leading into the laminating nip. These items need to be "de-curled" before laminating by rolling
them in the reverse direction and storing them in this position for a short period of time.
12.2 Laminating Film Join Splices
It is inevitable that a small proportion of film will contain a join spliced with red heat resistant tape.
These join splices, while undesirable, are unavoidable and must be considered a normal laminating
event. Every roll with a join splice contains a warning label.
If you receive a roll of film that contains a join splice, place it on the top film position so you can
watch for the spliced section during operation. When it appears, apply slack on the supply roll to
minimise the tension, and stop feeding items until the splice passes through the laminating rollers.
This procedure will prevent tearing of the roll and spoiling the item being laminated.
As an extra precaution the machine can be stripped just before a join and the splice cut out and the
web re-adhered to the original web still in the machine.
