<p>PROBLEM TO BE SOLVED: To provide a bottle made of a specified resin composition having a superior transparency, barrier property, shielding property against ultra violet rays, flavor and processability. SOLUTION: This bottle is formed by (a) 5 to 50 wt.% of a specified polyethylene naphthalene carboxylate and (b) 95 to 50 wt.% of a specified polyethylene terephthalate, wherein a compatibility degree of the polyester constituting the bottle is 0.15 to 0.50, a melting point of the polyester satisfies the equation: Tm<=254-28×[an amount of inclusion in a unit of EN in polyester constituting the bottle (%)/100], wherein the EN unit in this equation is meant by unit of ethylene naphthalene dicarboxylate, and an amount of acetaldehyde dispersed into the bottle is 10μg/L.day or less.</p> |
