摘要： A stretchable, fastening tape of the invention comprising a solid middle portion made of an elastic material and two solid end portions made of a non-elastic material which are integrally bonded through respective solid boundary regions to said solid middle portion, said end and middle portions having substantially the same structural dimension, and wherein said elastic material being, a composition comprising (a) and (b), or (a), (b) and (c) as defined below, and said non-elastic material is constituted of (d) as defined:(a) 100 parts by weight of a hydrogenated block copolymer represented by a general formula, A-(B-A).sub.n, wherein A is a block polymer of a monovinyl-substituted aromatic hydrocarbon, B is an elastomeric block polymer of a conjugated diene, the weight ratio of A to B being 20/80 to 40/60, and n is an integer of 1 to 4;(b) 10 to 80 parts by weight of a resin having a melting or softening point of 80.degree. C. or higher and an average molecular weight of 400 to 2,000;(c) 0 to 50 parts by weight of a thermoplastic olefin resin; and(d) a resin selected from the group consisting of polyethylene, polypropylene, poly(ethylene-propylene), poly(ethylene-vinyl acetate), and poly(styrene-butadiene), used alone or as a composite resin thereof.
