Pressure-Sensitive Adhesives
Designed to remain ready until pressure creates the bond.
Pressure-sensitive adhesives are used when a product must remain tacky and bond through contact and light pressure rather than heat, moisture, or a separate curing step.
HAR supports both hot melt and water-based pressure-sensitive technologies across permanent, removable, repositionable, and delayed-seal applications.

Adhesive, Coating and Equipment Expertise
Pressure-sensitive performance depends on both formulation and application control.
Coat weight, temperature, pattern, web handling, liner placement, and production speed all matter.
HAR can help evaluate the adhesive and, when needed, the equipment used to apply it.

When Pressure-Sensitive Performance Needs Improvement
A closure does not seal consistently.
Adhesive transfers to the liner or another surface.
Tack, peel, or shear performance is not balanced correctly.
A manual coating or application process is messy or slow.
A new substrate, liner, or product design requires testing.
The manufacturer wants to improve application accuracy or automate the process.
