ABSTRACT:
Pressure-sensitive adhesive compositions and an improved refastenable tape closure system comprising a release tape and a fastening tape wherein the fastening tape has a balance of properties such that the tape exhibits a maximum in the peel force between peel rates of 10 cm./minute and 400 cm./minute when peeled from a polyolefin substrate as found in disposable diaper back sheets are disclosed. The adhesive of the fastening tape comprises a specific range of compositions including an elastomeric component based on an A-B-A block copolymer wherein the A blocks are derived from styrene or alphamethylstyrene and the B block are derived from isoprene, butadiene, or hydrogenated versions of these or an (AB) block copolymer of the same type of composition in another geometry such as a tapered block copolymer or a radial block copolymer, a solid tackifier resin, a liquid tackifier resin, and an end block reinforcing resin.
