Peel and Adhesion Testing

Peel tests are used to measure the bond between two substrates. Most of these bonds are from adhesives.

Adhesion is the bond strength measurement of a coating to the substrate. Many physical, mechanical and chemical forces come into play when an adhesive is bonded to an item or surface and these forces may have an effect on each other. Before a product can be used these effects need to be tested.

Testing the adhesion properties is often associated with adhesives, tape, sealants, laminates, electronics, cosmetics, medical device packaging, general packaging seal strength and applications.
