Adhesive Failure - What is adhesive failure?
Definition of ADHESIVE FAILURE:
A partial or total lifting of a label from the substrate due to a failure of the adhesive.
Adhesive failure can be the result of a problem with the internal bond strength of an adhesive (cohesive failure) or the external bond strength of an adhesive (adhesive failure). Cohesive failure occurs when the internal strength of an adhesive is weaker than external forces, such as stress or pressure or the strength of an adhesive bond with an adjacent surface or surfaces, which results in the adhesive layer splitting so that some of the adhesive remains on the face material and some on the substrate (as adhesive residue). Adhesive failure occurs when the adhesion of an adhesive to a face material or substrate fails, resulting in the adhesive delaminating from the face material or the substrate (or both) as an individual layer.Go Back to Glossary
