Abstract

A heat-shrinkable polyester film comprising ethylene terephthalate as a main component, containing not less than 0 mol % and not more than 5 mol % of a monomer component capable of serving as an amorphous component relative to the total of a polyester resin component, and having a main shrinkage direction in a lengthwise direction, wherein the heat-shrinkable polyester film satisfies heat shrinkage characteristics of the width direction and the lengthwise direction and the molecular orientation angle difference which is a difference between a molecular orientation angle of an edge of one end in the width direction and a molecular orientation angle of an edge of the other end.
