Label having means of preventing deformation in a substrate

The present application relates to a label comprising a first layer being a paper layer or a polymer film layer and a second layer being a pressure-sensitive adhesive layer applied to one side of the first layer, characterized in that said label is provided with at least one flexible means and/or the pressure-sensitive adhesive is present in the form of a pattern. Furthermore, the present application also relates to a label sheet comprising in the following sequence: a backing material, a release layer, a pressure-sensitive layer and a top layer being a paper layer or a polymer film layer, wherein the top layer, being a paper layer or a polymer film layer, has detachment lines that are applied such that at least one sub-region is formed, characterized in that said sub-region(s) is (are) provided with at least one flexible means and/or that the pressure-sensitive adhesive is present in the form of a pattern.
