Heat shrinkable polyester film
The present invention provides a heat shrinkable polyester film whose hot water shrinkage along its main shrinkage direction is equal to or greater than 20% when the film is put in hot water of 70&deg; C. for 5 sec; 35% to 55% when put in hot water of 75&deg; C. for 5 sec; and 50% to 60% when put in hot water of 80&deg; C. for 5 sec, wherein the compressive strength of the label formed by the film satisfies a following expression (1):Y>X2.2&#8195;&#8195;(1)where y denotes compressive strength (mN) and x denotes film thickness (&mgr;m).
