The objective of the present invention is to provide an adhesive resin composition suitable for multilayer structures, which maintains sufficient bonding strength even when in contact with gasoline or light oil, while having excellent long-term durability, durability in terms of high-temperature fuels, and bonding strength at high temperatures. The present invention relates to an adhesive resin composition that is characterized by being composed of a modified ethylene polymer (A1) which is graft-modified by an unsaturated carboxylic acid or a derivative thereof and has a density within the range of 930-980 kg/m 3 and an unmodified ethylene polymer (A2) which has a density within the range of 910-929 kg/m 3 . The adhesive resin composition is also characterized by having a melt flow rate (MFR) of 0.1-3 g/10 min as determined in accordance with ASTM D 1238 (at 190°C, under a load of 2,160 g), a density of 920-930 kg/m 3 and an elution of 60% by weight or less as determined by cross-fractionation chromatography at 85°C or less. The present invention also relates to a multilayer structure which is obtained using the adhesive resin composition. |
