Claim:
Adhesive tape suitable for flying splice of flat web materials having non-polar surfaces, which flat web materials have been wound to form rolls, the adhesive tape comprising an upper self-adhesive composition, a splittable carrier and a lower self-adhesive composition on a bottom face of the splittable carrier, wherein the upper self-adhesive composition is a silicone-free self-adhesive composition that has a bond strength to a polyethylene substrate of 1.5 N/cm or more (measurement method tesa test A) and an initial tack corresponding to a rolling distance of 50 mm or less (measurement method tesa test D), and the lower self-adhesive composition is a self-adhesive composition that has a bond strength to a polyethylene substrate of 1.5 N/cm or more (measurement method tesa test A) and a complex viscosity of 10 000 Pa·s or more at 1 rad/s and 40° C. (measurement method tesa test F).
