Abstract
Object: To provide a resin composition having excellent oxygen barrier properties and transparency, and high tensile elongation at break; a molded article, a film, and a multilayer film. Resolution means: A resin composition including from 20 to 80 parts by mass of a polyamide resin (A) and from 80 to 20 parts by mass of a polyamide resin (B); wherein more than 35 mol % of all the constituent units of the polyamide resin (A) are constituent units including an alkylene chain having from 2 to 6 carbons; the polyamide resin (B) includes constituent units derived from a diamine and constituent units derived from a dicarboxylic acid, wherein 70 mol % or more of the constituent units derived from a diamine are derived from a xylylenediamine; from 30 to 70 mol % of the constituent units derived from a dicarboxylic acid are derived from an α,ω-linear aliphatic dicarboxylic acid having from 4 to 8 carbons; from 70 to 30 mol % of the constituent units derived from a dicarboxylic acid are derived from isophthalic acid, with the proviso that the total does not exceed 100 mol %; and the polyamide resin (B) further includes phosphorus atoms in a ratio of 3 to 300 mass ppm, and calcium atoms so as to be the ratio that phosphorus atoms:calcium atoms of 1:0.3 to 0.7.
