摘要： Adhesive tape for a bond which can be redetached by pulling, without residue and without damage, having a foam backing coated on one or both sides with a self-adhesive composition, characterized in thata) on at least one of the two sides of the foam backing there is applied a self-adhesive composition whose ratio of tear strength to stripping force (peel force) at a peel angle of less than 10.degree. to the bond surface is greater than 1.2:1,b) the foam backing is subjected to controlled pretreatment/damaging in such a way that the detachment force (stripping force) is lowered relative to an analogous self-adhesive tape with a foam backing which has not been correspondingly pretreated/damaged, andc) the foam backing does not have a tear strength which is sufficient for redetachment without residue or damage.
