WIPO Patent Application WO/2008/018528
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a package covered with a label formed from a heat-shrinkable film and having satisfactory tearableness. [MEANS FOR SOLVING PROBLEMS] The heat-shrinkable polyester film for label formation shrinks mainly in the machine direction. It has been regulated so as to have the following properties in respective given ranges: the degree of machine-direction hot-water thermal shrinkage through 10-second immersion in 90°C water; degree of transverse-direction hot-water thermal shrinkage through 10-second immersion in 90°C water; transverse-direction angle tear strength after 10% machine-direction shrinkage through immersion in 80°C water; Elmemdorf ratio determined through an Elmendorf tear load measurement made after 10% machine-direction shrinkage in 80°C water; and degree of natural shrinkage through 700-hour or longer aging in an atmosphere of 40°C and 65% RH.
