PROBLEM TO BE SOLVED: To obtain the subject resin composition that shows excellent appear ance, gas-barrier properties and continuous moldability and is useful as a food- packaging material by using a saponified product of a specific ethylene-vinyl acetate copolymer. SOLUTION: The objective resin composition includes at least three kinds of saponified products of ethylene-vinyl acetate copolymer (A) through (C) and the components (A)-(C) satisfy the following formula: Et(C)>=Et(B)+3, Et(B) >=Et(A)+3, Tm(C)<=165 [Ets are each the ethylene content (in mole %) of the saponified products of ethylene-vinyl acetate copolymer; Tm is the fusing peak temperature in deg.C of the saponified product of ethylene-vinyl acetate at the heating rate of 10 deg.C/min in the differential scanning calorimeter. In addition, in individual components A through C, the ethylene content is adjusted to about 10-70 mol.%, while MFR (melt flow rate at 210 deg.C under the load of 2160 g) is adjusted to about 0.1-100 g/10 minutes.
