A peel strength tester is a specialized device used to measure the adhesive bond strength between materials, such as labels, tapes, or packaging seals. By applying controlled force, it evaluates how well an adhesive holds under various conditions. This is essential for industries like packaging, automotive, and electronics, where durable bonds are critical for product quality and safety. With a peel strength tester, manufacturers ensure their adhesives meet strength standards, enhancing product reliability and customer satisfaction.
