Peel strength is the measure of the force required to separate two bonded materials such as tape, labels, and plastic films. It can also provide valuable information to evaluate the peel strength for sealed containers, trays, and pouches.
The strength is calculated during a test by pulling the sample at a constant rate of speed and averaging the force data collected over a defined distance or time and dividing this by the unit width of the sample. Results are commonly expressed as N/m or lb/in.
Depending on the material and application, peel testing can simulate actual product use and be tested at various peeling angles.
