    • A biaxially oriented polyester film to be laminated onto a metal plate and molded, which comprises a copolyester, said copolyester comprising (a) terephthalic acid in an amount of 82 to 100 mol % and 2,6-naphthalenedicarboxylic acid or a combination of 2,6-naphthalenedicarboxylic acid and other dicarboxylic acids in an amount of 0 to 18 mol % of the total of all dicarboxylic acid components and (b) ethylene glycol in an amount of 82 to 100 mol % and cyclohexanedimethanol or a combination of cyclohexanedimethanol and other diols in an amount of 0 to 18 mol % of the total of all diol components, and having (c) a glass transition temperature of 78.degree. C. or higher and (d) a melting point of 210 to 250.degree. C. The said film has the following relationship between the highest peak temperature (Te, .degree. C.) of loss elastic modulus and the glass transition temperature (Tg, .degree. C.): Te-Tg.ltoreq.30, or its content of a free dicarboxylic acid diol ester is 50 ppm or less. The said film has improved flavor retention properties for its contents taste, particularly taste and flavor retention properties after a retort treatment, while retaining excellent moldability, heat resistance, impact resistance.

    • Provided is a molten metal discharge nozzle capable of suppressing turbulence in a molten metal stream passing through an inner bore thereof, with a simple structure. A cross-sectional shape of a wall surface of the inner bore, taken along an axis of the inner bore, comprises a part or an entirety of a curved line expressed by the following formula: log(r(z))=(1/n)×log((Hc+L)/(Hc+z))+log(r(L)) (1), where: 6≧n≧1.5; L is a length of the nozzle; Hc is a calculative hydrostatic head; and r(z) is a radius of the inner bore at a position located a distance z downward from an upper end of the nozzle, wherein, in a graph where the distance z is plotted with respect to a horizontal axis (X-axis) thereof, and a pressure of molten metal at a center of the inner bore in horizontal cross-section at a position located the distance z is plotted with respect to a vertical axis (Y-axis) thereof, an approximation formula of a line on the graph is established without simultaneously including two or more coefficients having opposite signs, and wherein, on an assumption that the line is derived from an approximation formula based on a linear regression, an absolute value of a correlation coefficient of the line is 0.95 or more.
