ABSTRACT OF THE DISCLOSURE The present application is directed to improvements with respect to articles which are to be folded about an edge of a substrate. In particular, the invention is useful in multiple layer labels which have a plastic film cover of high tensile strength. These types of labels, when wrapped about the edge of a substrate, have a tendency to return to a less folded condition and thus, the adhesive layer which maintains the label in contact with the substrate must continuously offset this internal force. According to the present invention, this is overcome by structurally weakening the label at a predetermined location during the manufacture of the label to allow folding of the label in this predetermined location. This structure reduces the internal stress forces which tend to urge the label to a less folded condition. The invention also has application with respect to reinforcing films or other reinforcing materials which have a tendency, when folded, to return to a less folded condition.
