Abstract
Disclosed is a thermo-shrinkable polyester film having superior thermal shrinkage properties. The thermo-shrinkable polyester film has a strength of 3.5˜6.5 kg/mmin a direction perpendicular to a main shrinking direction at an initial elongation less than 10%, an elongation at rupture of 50˜700% in a direction perpendicular to a main shrinking direction, a thickness uniformity (ΔR) of 4 or less and a shrinkage ratio of 5% or less in a direction perpendicular to a main shrinking direction, thus preventing the rupture thereof in a rolling process and so on and ensuring process stability and productivity.
