<p>Self-adhesive tape comprising a laminate composed of at least two pressure-sensitive adhesive (PSA) layers A and B laminated directly to one another, one or both of the surfaces to be laminated to one another of the PSA layers A and B having been chemically and/or physically pretreated prior to lamination, and the shear strength tSA/B of the self-adhesive tape at 25° C., 40° C. and 70° C. under a weight load of 1000 g being at least 80% of the shear strength tSo of the PSA layer A and/or of the PSA layer B, where tSo represents the shear strength of the PSA layer having the lower shear strength.</p> |
