<p>PROBLEM TO BE SOLVED: To provide an injection molded body that can exhibit both oxygen barrier performance and oxygen absorption performance, is excellent in transparency and is very small in strength decrease observed as oxygen absorption proceeds.SOLUTION: The injection molded body comprises a resin composition including (A) a polyamide compound and (B) a polyester resin. The polyamide compound (A) contains 25-50 mol% of a diamine unit including 50 mol% or more of a specific diamine unit, 25-50 mol% of a dicarboxylic acid unit including 50 mol% or more of a specific dicarboxylic acid unit and 0.1-50 mol% of a specific constitutional unit. The polyester resin (B) contains a dicarboxylic acid unit including 0.01-15.0 mol% in total of units selected from a sulfophthalic acid unit and a sulfophthalic acid metal salt unit, and a diol unit.</p> |
