g / 10 min) is preferable, and when the melt index is smaller than the range, the inside of the extruder becomes in a high torque state at the time of molding to make extrusion difficult, and when the melt index is larger than the range, a molded product is formed. Is not preferable because of insufficient mechanical strength.

The EVOH (A) is obtained by saponifying an ethylene-vinyl acetate copolymer, and the ethylene-vinyl acetate copolymer can be produced by any known polymerization method, for example, solution polymerization, suspension polymerization, It is produced by emulsion polymerization or the like, and saponification of an ethylene-vinyl acetate copolymer can be performed by a known method.
