A polyester-based resin composition that exhibits good shrinkage characteristics, has a good shrinkage finish during shrinkage processing of the film, has excellent heat resistance, and is suitably used for a polyester heat-shrinkable film with little deterioration over time, Provision of heat-shrinkable films, heat-shrinkable labels and containers. A polyester resin composition containing a predetermined amount of a predetermined polyester resin (A) and the following polyester resin (B) is used. (A) A polyester resin comprising a dicarboxylic acid residue component containing a predetermined amount of an alicyclic dicarboxylic acid residue, and a diol residue component having an ethylene glycol residue as a main component. (B) A dicarboxylic acid residue component mainly composed of an aromatic dicarboxylic acid residue other than an isophthalic acid residue, a predetermined aliphatic diol residue, and, if necessary, an alicyclic diol residue as a main component. A polyester resin comprising a diol residue component. [Selection figure] None |
