Zusammenfassung:	A hotmelt adhesive comprises a block copolymer (17 - 30 wt.%), a tackifier and a plasticizer. The block copolymer comprises styrene-butadiene-styrene block copolymer (A) (at least 30 wt.%) containing (wt.%) styrene (35 - 50) and styrene-butadiene diblock (50 - 80); and has a viscosity of 15 wt.% toluene solution at 25[deg]C of 20 - 40 mPa.s. An independent claim is included for a disposable product obtained by applying the hotmelt adhesive at =130[deg]C in a non-contact manner.
