The present invention is characterized by containing an ethylene polymer (A) containing an ethylene polymer graft-modified with an unsaturated carboxylic acid or a derivative thereof, and satisfying the following requirements (1) to (4). Adhesive resin composition. (1) The melt flow rate (MFR) measured based on ASTM D 1238 at a temperature of 190 ° C. and a load of 2160 g is 0.1 to 3 g / 10 minutes. (2) The density is 910 to 930 kg / m 3 . (3) In the crystallization elution fractional chromatography measurement, the ratio of the eluted components at 50 ° C. or lower is 20% by mass or more. (4) In the crystallization elution fractional chromatography measurement, the ratio of the eluted components at 90 ° C. or higher is 25% by mass or more. The adhesive resin composition of the present invention has excellent adhesive strength to gas barrier resins such as ethylene / vinyl alcohol copolymers. Therefore, in the laminate containing the adhesive layer containing the adhesive resin composition and the gas barrier resin layer in direct contact with the adhesive layer, an additive is added to the gas barrier resin layer for softening. Even in such a case, since the two layers are firmly adhered to each other, peeling is unlikely to occur between the two layers. Therefore, the laminate can be effectively used as a packaging, a container, or the like having a high barrier property. |
