Abstract
A series of labels remain supported on a liner after a matrix of waste label material has been stripped from the liner. The adhesion of the matrix to the liner is weakened prior to stripping of the matrix by mechanically disturbing without severing, as by embossing, areas of the construction where the matrix overlies the liner. Areas where the leading ends of labels overlie the liner may also be similarly disturbed to make eventual peeling of the liner from the labels easier. In another aspect, the construction may be precrushed with a blunt die prior to die-cutting of the labels to eliminate "halo" effect upon stripping of the matrix.
