Delamination
Cause:
Refers to either one of two conditions; 1) the adhesive separating from the laminate substrate,
or 2) the laminate separating from the product being laminated.
or 2) the laminate separating from the product being laminated.
Solution:
Delamination is eliminated by using the correct type of film for the type of media being used
and setting the machine to the optimal operating parameters.
and setting the machine to the optimal operating parameters.
Out gassing
Cause:
The term that describes the phenomenon where the heat from the laminating process turns
components of the printed media into a gas. This is seen as a cloudy or murky finished
image. It can also be caused by a chemical incompatibility between the overlaminate’s adhesive
and the printed media.
components of the printed media into a gas. This is seen as a cloudy or murky finished
image. It can also be caused by a chemical incompatibility between the overlaminate’s adhesive
and the printed media.
Solution:
Heat related out gassing may be eliminated by reducing the operating temperature or
increasing the speed. If out gassing is due to incompatibility, it will be necessary to change
film or media.
increasing the speed. If out gassing is due to incompatibility, it will be necessary to change
film or media.
Silvering
Cause:
A term used to describe one of two occurrences; 1) air bubbles trapped between the product
and a thermal laminate, generally caused by insufficient heat being applied to the laminator
or 2) the adhesive not fully activated in a pressure sensitive film, which will disappear once
the adhesive is fully activated. This activation process can be sped up if a small amount of
heat is applied during the application.

heat is applied during the application.
Solution:
Ensure your set point for the type of film being used is correct. You may also decrease the
speed which will increase the dwell ( time in the laminating rollers nip ) time which allows the
film more time to absorb the heat to activate the adhesive.
