Apparatus for testing the mechanical strength of flexible packing materials and packing material composites

摘要

Apparatus for testing the mechanical strength, in particular the interlaminar strength and the resistance to delamination, of flexible packing materials and packing material composites such as gluing seams in flexible packing materials. A sample (1, 2, 3) of the packing material or of the longitudinal gluing seam (1) joining two packing material parts is cleaved by means of a roller (8) bonded (4) to the surface of the sample and having a force acting perpendicularly to its surface and transversely to the longitudinal direction of the gluing seam, with a constant cleavage angle (linear cleavage loading, transverse peeling test). <IMAGE>
