PROBLEM TO BE SOLVED: To obtain a modifying composition which shows excellent slip during melt molding, is reduced in the formation of a resinous deposit around a die, and can give a molding free from die lines and excellent in appearance by compounding an ethylene/vinyl acetate copolymer saponificate (EVOH) with an oxide and a higher fatty acid in a specified ratio. SOLUTION: The oxide and the higher fatty acid are each used in an amount of 0.001-10 wt.%. The EVOH used is usually one having an ethylene content of 20-60 mol% and a degree of saponification of at least 90 mol%. It is desirably one having a melt index of 0.1-100 g/10 min at 210 deg.C under a load of 2,160 g. The oxide used is exemplified by silicon oxide, aluminum oxide, cerium oxide, tungsten oxide, molybdenum oxide, or a compound product thereof. The higher fatty acid used is exemplified by a higher fatty acid, a higher fatty acid metal salt, a higher fatty acid ester, or a higher fatty acid amide. EVOH is useful as a resin which is to be modified.
