Advances in testing & characterization of rigid & flexible packaging structures

THE PEEL strength is the measure of the average force to part two bonded materials like tape, labels, textile or plastic films. The strength is calculated during a peel test at a constant speed rate by divided the average force required during the test by the unit width of the bonded samples. Depending on materials, norms, products, the tests can be done with different angles: 90°Candl80°C are commonly used. The peel tests can be performed on containers such as jars, cans, trays, yogurt, applesauce or pockets and pouches. In this case, tests are available at different angles which can be close to the product use. Peel test at 45° for example.
