Abstract

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.
