| 摘要 |
The invention relates to an elasticated absorbent article wherein the elastication is provided by an elastomeric hot melt adhesive composition comprising at least one thermoplastic elastomer and at least one tackifying resin, the thermoplastic elastomer(s) being a styrene/butadiene/styrene (SBS) block copolymer or a blend of styrene/butadiene/styrene with styrene/isoprene/styrene (SIS) block copolymer on which SIS is present in an amount equal to or less than 50% by weight of the total block copolymer the composition being characterised in that: a) it is capable of bonding, when applied from the molten state, to plastic and/or cellulosic materials with a 90.degree. peel force of not lower than 0.5 N/cm (as herein defined). b) it has a tensile strength retention after 50 cycles (as herein defined) of at least 40%; and c) it has a viscosity of 120,000 cps or less at 180.degree.C and an applied shear of 80 sec-1. The elastomeric hot melt adhesive is optionally foamed. The absorbent article may be for example a baby diaper, diaper for incontinent adults, an incontinence garment, a sanitary napkin or a pantiliner.
