The invention relates to a heat shrink label (4) and a multilayer face film of the label (4). According to an embodiment multilayer face film is oriented in one direction. The multilayer face film includes at least one layer comprising first cyclic olefin copolymer and second cyclic olefin copolymer and the first cyclic olefin copolymer is different from the second cyclic olefin copolymer. A glass transition temperature of the first cyclic olefin copolymer and the second cyclic olefin copolymer is between 50 and 90° C. Further the application concerns a combination of a label (4) and an item (8), a method for providing a heat shrink label (4), a method for labelling an item (8) and a method for separating a label (4) from an item (8) labelled.
A heat shrink label comprising a multilayer face film oriented in one direction, the multilayer face film including a first skin layer comprising first cyclic olefin copolymer and second cyclic olefin copolymer, wherein the first cyclic olefin copolymer is different from the second cyclic olefin copolymer, and wherein a glass transition temperature of the first cyclic olefin copolymer and the second cyclic olefin copolymer is between 50 and 90° C., the multilayer face film further comprising a second skin layer comprising a first cyclic olefin copolymer and a second cyclic olefin copolymer, wherein the first cyclic olefin copolymer and the second cyclic olefin copolymer are the same as the first cyclic olefin copolymer and the second cyclic olefin copolymer of the first skin layer;
A combination of a heat shrink label and an item, wherein the label comprises a continuous multilayer face film around an external surface of the item, wherein the continuous multilayer face film is oriented in one direction and comprises a first skin layer comprising first cyclic olefin copolymer and second cyclic olefin copolymer, wherein the first cyclic olefin copolymer is different from the second cyclic olefin copolymer, and wherein a glass transition temperature of the first cyclic olefin copolymer and the second cyclic olefin copolymer is between 50 and 90° C., the multilayer face film further comprising a second skin layer comprising a first cyclic olefin copolymer and a second cyclic olefin copolymer, wherein the first cyclic olefin copolymer and the second cyclic olefin copolymer are the same as the first cyclic olefin copolymer and the second cyclic olefin copolymer of the first skin layer:
