PROBLEM TO BE SOLVED: To provide an ethylene-vinyl alcohol-based polymer alloy composition excellent in oxygen gas barrier properties and also excellent in moisture resistance, a film comprising the composition, a packaging material including the film, and a method for producing the composition. SOLUTION: The ethylene-vinyl alcohol-based polymer alloy composition comprises a mixture of 85.0-94.0 mass% of an ethylene-vinyl alcohol copolymer and 6.0-15.0 mass% of an acid-modified polypropylene, and has a water absorption percentage of 11.0% or less in 24-hour immersion time specified by JIS K7209.
