Beschreibung
Zusammenfassung:	The present invention relates to an adhesive resin composition optimal for a cover material for a polyester-based resin container, having excellent film-forming properties and excellent easy opening for polyester-based resin containers, and providing a sense of good peeling by suppressing knocking and peeling, and a sheet, a cover material, a member set for a sealed container, and a container using the same. The task of the present invention can be solved by the adhesive resin composition which includes 10-45 mass % of ethylene-α olefin copolymer (A) with a density of 0.80-0.95 g/cm3, and a melt flow rate of 20-40 g/10 minutes; 35 to 65 mass% of the ethylene-vinyl acetate copolymer (B) with a vinyl acetate content of 5 to 15 mass% and a melt flow rate of 1 to 10 g/10 min; and 10-30 mass % of tackifying resin (C).
