PROBLEM TO BE SOLVED: To provide a packing for doorstop by using a thermoplastic elastomer that has a sufficient adhesion in a two color formation with an ABS resin. SOLUTION: The objective doorstop packing is produced by simultaneously extruding a thermoplastic elastomer composition comprising the following (a) through (c) and an ABS resin respectively from separated extruders and the extruded polymer compositions are introduced into one dice to form a fusion- bonded packing: (a) 10-50 wt.% of a hydrogenated block copolymer prepared by hydrogenating a block copolymer comprising a chain-terminal polymer block A mainly comprising at least two vinyl aromatic compounds and an intermediate polymer block B mainly comprising at least one conjugated diene, (b) 5-30 wt.% of a hydrogenated block copolymer modified with a polar group and (c) 40-50 wt.% of a thermoplastic polyurethane.
