摘要： A heat-shrinkable polyester film is obtained which is extremely satisfactory in openability along a perforation, has exceedingly high productivity, and is less apt to split in the lengthwise direction in processing, e.g., printing. Provided is a label which is formed from the heat-shrinkable film and is satisfactorily tearable. The label is one formed from a tubular material which comprises as a base a heat-shrinkable film thermally shrinking mainly in the film width direction and which has been cut according to an object to be packaged, both edges in the film width direction having been bonded to each other. The tubular material has been thermally shrunk to constitute the label, with which at least part of the periphery of the object to be packaged is covered. The label has an angle tear strength in the direction perpendicular to the main shrinkage direction (i.e., in the film length direction) of 100-310 N/mm and a tensile break strength in the direction perpendicular to the main shrinkage direction (i.e., in the film length direction) of 50-300 MPa.

摘要： A heat-shrinkable polyester film which causes the main shrinkage in the lengthwise direction and which is controlled in such a way that the lengthwise and widthwise heat shrinkage factors observed when treated in warm water of 90°C for 10 seconds, the lengthwise and widthwise refraction indexes, and the natural shrinkage factor observed after the aging at 40°C and 65%RH for 700 hours fall within prescribed ranges respectively. The heat-shrinkable polyester film can be produced by stretching an unstretched film at a temperature ranging from the Tg plus 5°C to the Tg plus 40°C at a draw ratio of 2.5 to 6.0 in the widthwise direction, passing the resulting film through an intermediate zone not accompanied with positive heating, heat-treating the film at 100 to 170°C for 1.0 to 10.0 seconds, cooling the film to lower the surface temperature of the film to a temperature of 30 to 70°C, stretching the film at a temperature ranging from the Tg plus 5°C to the Tg plus 80°C at a draw ratio of 2.0 to 7 in the lengthwise direction, and then cooling the film at a cooling rate of 30 to 70°C/sec to lower the surface temperature of the film to a temperature of 45 to 75°C.
