Adhesive tape, which is suitable for the flying roll change of flat web material that is wound upon rolls and has nonpolar surfaces and which comprises an upper self-adhesive compound (1, 11), a splittable backing (2, 12) and a lower self-adhesive compound (3, 13) on the lower side of the splittable backing (2, 12), wherein a silicone-free self-adhesive compound with an adhesive strength on a polyethylene adherend surface of 1.5 N/cm or more (measuring method tesa test A) and a tackiness corresponding to a rolling distance of 200 mm or less (measuring method tesa test D) is used as the upper self-adhesive compound (1, 11) and a self-adhesive compound with an adhesive strength on a polyethylene adherend surface of 1.5 N/cm or more (measuring method tesa test A) and a complex viscosity of 10,000 Pa s or more at 1 rad/s and 40°C (measuring method tesa test F) is used as the lower self-adhesive compound (3, 13). |
