主权项

1. A melt-molded article comprising an ethylene-vinyl alcohol copolymer resin composition which comprises:
an ethylene-vinyl alcohol copolymer resin; and a phosphoric acid compound (D); wherein a ratio (d/t) of the content (d: μmol/g) of the phosphoric acid compound (D) in terms of phosphate radical to a content (t: μmol/g) of phosphorus element is 0.4 or less, wherein the content (d) of the phosphoric acid compound (D) is determined by ion chromatography analysis of a solution obtained by extraction of the melt-molded article with 0.01 N aqueous HCL solution at 95° C. for 4 hours, and the content (t) of phosphorous element is determined by high-frequency plasma emission spectrochemical analysis of a solution of combustion ash, the combustion ash being obtained by complete burning of the melt-molded article by an oxygen-flask combustion technique.
