<P>PROBLEM TO BE SOLVED: To provide a thermally shrinkable polyester-based film which does not cause the shortage of shrinkage, when heated, and is extremely excellent in natural shrinkage resistance. <P>SOLUTION: The thermally shrinkable polyester-based film is characterized in that a natural shrinkage rate in the main shrinking direction is ≤0.30%, after stored for 40°C×30 days, and a shrinkage rate in the main shrinking direction is ≥20% and <80%, when the film is dipped in 80°C hot water for 10 seconds. <P>COPYRIGHT: (C)2012,JPO&INPIT |
