A multi-layered packaging container superior in crack resistance, said container being made up of an outer layer of thermoplastic resin and an inner layer of saponified product of ethylene-vinyl acetate copolymer characterized in that the ethylene content is 25 to 60 mole %, the degree of saponification of the vinyl acetate component is higher than 96 mole %, the melt viscosity index is lower than 1, the specific gravity (d) is in the range specified by the formula (1) below, and Y1 and Y2 are in the range specified by the formula (2) below: 1.274-4.4x10-3X<d<1.332-4.4x10-3X (1) ¦Y1-Y2¦</=1 (2) where d is the specific gravity of EVOH resin at 25 DEG C., X is the ethylene content (mole %) of EVOH resin, and Y1 and Y2 are the melt viscosity indices of the thermoplastic resin and the saponified product of ethylene-vinyl acetate copolymer, respectively.
