Delamination - What is delamination?

Answer:

The separation of a laminate (multi-layered) material into its individual layers. Delamination is usually an undesirable material failure and can involve the separation of two adjacent layers or multiple layers within a laminate or construct.

In labelling, delamination can involve the separation of a coating from the face material, the separation of the face material from the adhesive, or the separation of a label from its backing sheet during manufacture or printing.
