Liner and also the use thereof

1. Liner comprising a nucleated film which comprises monoaxially oriented polypropylene having a flexural modulus of at least 1400 and a release coating being applied on at least one of the two outer sides of the film, wherein the film has a draw ratio of at least 1:8, a tensile strength in machine direction of at least 300, a stress in machine direction at 1% extension of at least 20 and/or a stress at 10% extension of at least 250.

2. Liner according to claim 1 , wherein the film has a thickness of between 25 and 200 μm.

3. Liner according to claim 1 , wherein a release coating is applied on both outer sides of the film, the release coating optionally having different release forces with respect to a layer of adhesive.

4. Liner according to claim 1 , wherein the film, on at least one of the two outer sides, has a coextrusion layer comprising a polypropylene polymer or an ethylene-containing polymer having a crystallite melting point of below 150° C., the coextrusion layer being disposed optionally between the film and the release coating.

5. Liner according to claim 1 , wherein the film, on at least one of the two outer sides, has a coextrusion layer comprising a polypropylene polymer having an olefinic comonomer content of less than 2.5% by weight, the coextrusion layer optionally being free from nucleating agent and the coextrusion layer being disposed optionally between the film and the release coating.

6. Liner according to claim 1 , wherein the film is coloured.

7. Liner according to claim 1 , wherein the release coating is a silicone layer.

8. A combination comprising a liner according to claim 1 applied to an adhesive layer of a single-sided or double-sided adhesive tape, adhesive-tape diecut or label.

9. Combination according to claim 8 , wherein the adhesive coating is acrylate-based.
