An object of the present invention is to provide a white heat-shrinkable polyester film roll that satisfies the following requirements. Even if the width of the white heat-shrinkable polyester film roll containing titanium oxide is widened, the use of cut-out labels can be suppressed. Processing problems occur while processing is in progress.n n n (1) film roll length is 1000m to 20000m, film width is 400m to 10000mm; (2) the heat shrinkage rate in the main shrinkage direction is 50% to 85%; (3), (4) the maximum value of the heat shrinkage rate in the main shrinkage direction and The difference between the minimum value is 0% to 3% when sampling in the width direction of the film, and 0% to 3% when sampling in the length direction of the film; (5), (6) The difference between the maximum and minimum values of apparent specific gravity is between When sampling in the film width direction, it is 0 g / cm 3 to 0.01 g / cm 3 , and when sampling in the film length direction, it is 0 g / cm 3 to 0.010 g / cm 3 . |
