PROBLEM TO BE SOLVED: To provide a package having good tearing of a label consisting of a heat-shrinkable film. SOLUTION: At least a part of an outer periphery of the package is covered with a label consisting of a heat-shrinkable film as a base material and heat-shrunk. The right-angle tear strength in the direction orthogonal to the main shrinkable direction per unit thickness of the label is≥100 N/mm and≤300 N/mm. The Young's modulus before breakage in the main shrinkable direction of the label is≥0.05 GPa and≤0.15 GPa. COPYRIGHT: (C)2009,JPO&INPIT
