Label Release Liner Report: Developments, Innovations and Challenges

Choosing the right silicone release system
The challenge of choosing the right silicone release system and pressure-sensitive adhesive to partner a pressure-sensitive label for a particular application is the subject of an ongoing study conducted by Henkel Corp. Henkel’s global marketing manager for pressure-sensitive adhesives, Ingrid Brase, demonstrated that it is essential to consider liner release performance requirements as well as silicone selection when evaluating adhesives. While adhesive tackifier chemistry and rubber type did not seem to affect release force, she concluded, there is a strong inverse relationship between stiffer adhesives and release force, with a lower release force needed for stiffer adhesives.
