Hot Melts Hold Fast

The quality of pressure-sensitive adhesive (PSA) labels and tape is often judged long after products are wound and packaged. These products can be subject to wide swings in temperature and other environmental conditions well before they are called into action months later. Yet when the time comes, the adhesive must release cleanly from the liner, without tears or undue tack. Adhering too strongly (or releasing too early) can frustrate customers, and in high-speed food and beverage labeling operations, delays can be costly.
