Abstract: A binding tape exhibits high sound absorbing performance and suppressed breaking of the tape during the binding work. The binding tape includes a substrate layer of a nonwoven fabric and an adhesive layer that contains an adhesive and that is provided on at least either surface of the substrate layer, where: the nonwoven fabric is formed from fibers at least partially containing a thermoplastic elastomer; and the nonwoven fabric has a tensile breaking strength in the tape longitudinal direction (A1) of 20 N/10 mm or more.

Abstract: A hot melt adhesive composition which can realize moderate adhesive strength with respect to the adherend when porous substrate is used, the composition, including: a styrene-based block copolymer; a tackifier; and a plasticizer; wherein: the styrene-based block copolymer is a styrene-butadiene block copolymer and a butadiene portion thereof is partially hydrogenated; the tackifier is contained by 65 to 190 parts by mass with respect to 100 parts by mass of the styrene-based block copolymer; and the plasticizer is contained by 0.1 to 24 parts by mass with respect to 100 parts by mass of the styrene-based block copolymer.
