Glossary

In the context of adhesive label printing, adhesion refers to the bonding or sticking ability of an adhesive to a substrate or surface. It is the strength and durability of the bond between the label and the surface to which it is applied.

The adhesion of a label is a critical factor in ensuring that the label remains securely attached to the substrate throughout its intended use. Proper adhesion is important to prevent issues such as label lifting, peeling, or premature detachment, which can affect the functionality and appearance of the label.

Adhesion testing is often performed to evaluate the strength and performance of adhesive labels. This involves subjecting the labels to various tests, such as peel adhesion tests, shear tests, or lap shear tests, to measure the force required to separate the label from the substrate.
