    摘要： The invention aims at providing a heat-shrinkable polyester film which is excellent in tearability along perforations and in break resistance after storage when used as labels of beverage bottles. The invention relates to a heat-shrinkable polyester film which is made of a polyester resin comprising ethylene terephthalate as the main constituent and containing at least 13 mol % of at least one monomer capable of forming an amorphous component in the whole polyester resin component and which has specific heat shrinkage characteristics and exhibits specific mechanical characteristics after heat shrinking treatment. The film can be produced by a sequential biaxial orientation process comprising longitudinal orientation step, intermediate heat treatment step, positive cooling step, transverse orientation step, and final heat treatment step.

    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.
