Disclosed is a thermo-shrinkable polyester film in which shrinkage uniformity is ensured in a shrinking process thus realizing superior quality of the outer appearance without causing a poorly printed state, reducing the production cost of the shrinking process and improving the productivity.

Thermo-shrinkable polyester film

Disclosed is a thermo-shrinkable polyester film having superior thermal shrinkage properties. The thermo-shrinkable polyester film has a strength of 3.5&#x2dc;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&#x2dc;700% in a direction perpendicular to a main shrinking direction, a thickness uniformity (&#x394;R) 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.
