ABSTRACT:
An adhesive resin composition comprises (A) 2 to 98% by weight of an ethylene copolymer resin containing 0.01 to 20% by weight of the unit of an unsaturated carboxylic acid anhydride in the main chain; and (B) 98 to 2% by weight of a resin mixture comprising (i) 50 to 90% by weight of a copolymer resin of ethylene/vinyl acetate, (ii) 40 to 9.5% by weight of a binary copolymer resin of ethylene and an .alpha.-olefin having 3 to 12 carbon atoms, and (iii) 10 to 0.5% by weight of an ethylene/propylene/unconjugated diene terpolymer. The resin mixture is obtained by mixing (i), (ii) and (iii) in a molten state and has a toluene extraction residue of 10 to 60% by weight. The adhesive resin composition is utilized as an adhesive material between layers of a multi-layer laminate and scrap or waste material from the adhesive resin composition or from the multilayer laminate can be recycled as an adhesive resin composition having excellent interlayer strength and compatibility.
