The invention relates to an adhesive tape comprising a backing consisting of a film to which an adhesive is applied on at least one side, wherein the film is a uniaxially stretched film which consists to at least 95 wt.%, preferably at least 99 wt.%, particularly preferably 100 wt.%, of propylene polymer compositions which have different phases and comprise the following components: i)80 to 99 wt.%, preferably 93 to 96 wt.%, of a propylene polymer matrix, which comprises, relative to the total weight of components i) and ii), a propylene homopolymer and particularly preferably a random propylene copolymer having a structure selected from ethylene or C 4 To C 10 A comonomer of an alpha-olefin, the propylene polymer matrix having a comonomer content of no more than 15 wt%; ii) from 1 to 20% by weight, preferably from 4 to 7% by weight, of an elastomer in the form of an ethylene-propylene copolymer having an ethylene content of from 50 to 90% by weight, relative to the total weight of components i) and ii). |
