Decaling is where you laminate items and then
mount them on other materials such as Foam Core
or mounting board. It is performed in two passes.
The rst pass laminates and applies the mounting
adhesive, encapsulating the item. The second pass
mounts it on rigid material.
This two pass operation requires pressure sensitive
laminating lm on the top supply shaft and pressure
sensitive mounting lm on the bottom supply shaft.
Refer to “Fig. 6-14. Congurations for Poly-in and
Poly-out Films.” for the proper conguration of
Poly-in or Poly-out lm.
