A heat-shrinkable polyester-based film is provided, which is heat-shrinkable in the longitudinal direction and which is freed from various problems, particularly curling-up or peeling in a bonded area. The heat-shrinkable polyester-based film is characterized by an A1/A2 (absorbance) ratio in the longitudinal direction, which is the main shrinking direction of the film, of 0.55 to 1, with an A1/A2 ratio in the width direction perpendicular to the main shrinking direction of 0.5 to 0.9, wherein A1 is the absorbance of the film at 1340 cm.sup.1 and A2 is the absorbance of the film at 1410 cm.sup.1 as determined by polarized ATR-FTIR spectroscopy, and a hot-water shrinkage of 35 to 60% in the longitudinal direction of the film and 3 to 12% in the width direction of the film, wherein the hot-water shrinkage is determined by dipping the film in hot water at 90 C. for 10 seconds.

Disclosed is a method for manufacturing a film. 50 wt % to 85 wt % of a first polyester and 50 wt % to 15 wt % of a second polyester are dried and mixed to form a mixture. The first polyester is polyethylene terephthalate (PET), polyethylene naphthalate (PEN), or combinations thereof. The second polyester is copolymerized of 1 part by mole of terephthalic acid, m parts by mole of 1,4-cyclohexanedimethanol (1,4-CHDM), n parts by mole of 1,3-cyclohexanedimethanol (1,3-CHDM), and o parts by mole of ethylene glycol (EG). m+n+o=1, 0o0.4, 0.6m+n1, and 0.06n/m1.31. The mixture is melted and blended to form a polyester composition, which is extruded to form a sheet. The sheet is then biaxially stretched to obtain a film. The biaxially stretched film is then treated with a thermal setting.
