摘要：
The present invention is directed to an ethylene-vinyl alcohol copolymer resin composition that contains 0.1 to 20 µmol/g, in terms of alkali metal, of an alkali metal salt (A), 0 to 2 µmol/g of a carboxylate radical (C1) which is extracted through an immersion treatment in water at 95°C for 10 hours, and 0 to 40 µmol/g of a carboxylate radical (C2) which is extracted through an immersion treatment in a 0.05 N aqueous sodium hydroxide solution at 95°C for 10 hours.
