See full text

What is provided is a heat-shrinkable film and a heat-shrinkable label that, when applied to a container in which the difference between the diameter of the body portion and the diameter of the mouth portion is large, sufficiently shrink in the mouth portion and do not easily allow the generation of a wrinkle or a sink mark in the mouth portion. The heat-shrinkable film contains polyester, a dicarboxylic acid component that constitutes the polyester contains 95 mol % or more of terephthalic acid, and a diol component that constitutes the polyester contains 50 mol % or more of ethylene glycol and 15 mol % or more of cyclohexanedimethanol. The shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 70° C. for 30 seconds is 20% or less, the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 80° C. for 30 seconds is 45% to 65%, and the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 98° C. for 30 seconds is 65% or more.
