BS EN 1719 determines the “loop tack” measurement for coated pressure-sensitive adhesives. This standard is primarily used by manufacturers of paper and board, packaging, and disposable sanitary products to measure the strength of things such as envelope adhesives and diaper tab adhesives. To create specimens for this test, adhesive strips are formed into a loop and gripped together. The adhesive loop is brought down into contact with a flat rigid plate at a rate of 5 mm/s. When the loop contacts the plate over approximately 25 mm by 25 mm, the adhesive loop is pulled upwards at a rate of 5 mm/s and the maximum force to fully separate the loop from the plate is recorded.
