The invention relates to a label laminate and a release liner of the label laminate. According to an embodiment release liner comprises a substrate comprising propylene block copolymer. The substrate may be oriented in a machine direction of the substrate. The substrate may have an elongation of the substrate in a machine direction of the substrate is less than 3% at a tension level between 200 and 1200 N/m. The substrate may have a ratio of 1% secant modulus in machine direction of the substrate to elongation in transverse direction of the substrate is between 2 and 15. Further the invention relates to a use of a release liner for self-adhesive label laminate and to a method for providing a label laminate.
A release liner for a label laminate, wherein the release liner comprises a substrate having a multilayer structure comprising at least a core layer, a first skin layer and a second skin layer, and wherein each of the layers comprise at least 38 weight percent propylene block copolymer and at most 60weight percent of at least one of propylene homopolymer and propylene random copolymer,
A label laminate comprising a face stock, a release liner and an adhesive layer between the face stock and the release liner, wherein the release liner comprises a substrate having a multilayer structure comprising at least a core layer, a first skin layer and a second skin layer, and wherein each of the layers comprise at least 38 weight percent propylene block copolymer and at most 60 weight percent of at least one of propylene homopolymer and propylene random copolymer,
