<p><P>PROBLEM TO BE SOLVED: To provide a polyester film having sufficient flexibility in which volatilization, exudation and bleed out of an oligomer component and a plasticizer when used as a molded product are suppressed. <P>SOLUTION: The polyester film consists mainly of a polylactic acid-based polymer and has 0.1-2 GPa initial tensile modulus at 23°C and≤2 wt.% lactic acid oligomer component content in the film. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
