Peeling of Covers or Sealing Materials (Peel Test)

The ability to peel off dimensionally stable or inflexible packagings depends on material combinations, machine parameters as well as on sealed seam and tear-off geometries. A test of the peel forces with a special peel test kit can help to optimize these elements. The most important value is the cracking force but the regularity of the sealing is also significant.  

A benefit of the Zwick peel test kit is the exact alignment of the delaminated area with the test axis: The packaging is tracked automatically by the sliding specimen table and this ensures a consistent and reproducible measurement of the load because the peeling angle of 90° is always guaranteed. Furthermore the kit enables a flexible adjustment to fit to different packaging shapes and heights.
