Abstract
The inventive label is prepared from a polyester with an intrinsic viscosity of 0.58 dl/g or more. The label has a base film with a thickness of 8-30 μm and a difference in specific heat capacity ΔCp between temperatures lower and higher than Tg of 0.2 J/(g·° C.) or more. The label has a tensile elongation at break of 5% or more in both a main shrinkage direction and an orthogonal direction. A difference between the absorbancy ratio (absorbancy at 1340 cm/absorbancy at 1410 cm) in the main shrinkage direction of the label and the absorbancy ratio in the direction orthogonal to the main shrinkage direction of the label is 0.2 or more. The label has a difference between a maximum value and a minimum value of a length in a vertical direction of the label of 3 mm or less.
