The invention relates to elastomeric hot melt adhesive composition comprising a thermoplastic elastomer and a tackifying resin, the thermoplastic elastomer(s) being a styrene/butadiene/styrene (SBS) copolymer or blend of styrene/butadiene/styrene with styrene/isoprene/styrene (SIS) in which SIS is present in an amount equal to or less than 50 % by weight of the total block copolymer, the composition being characterized in that: a) it is capable of bonding, when applied from the molten state, with plastic and/or cellulose materials, with a 90 degree peel force not lower than 0.5 N/cm; b) it has a tensile strength retention after 50 cycles of at least 40 %; c) it has a viscosity of 120,000 cps or less at 180 degree C and applied shear of 80 sec-1. |
