摘要： A polyester film according to an embodiment includes a polyester resin. The polyester resin includes a repeating unit having a cyclohexane skeleton and a repeating unit having a benzene ring. The polyester film has a base peak related to bending vibration of the benzene ring and a first peak related to C—O stretching vibration in a spectrum measured using a Fourier transform infrared spectrometer (FT-IR). The base peak is a peak at a wavenumber of 788 cm−1 to 798 cm−1. The first peak is a peak at a wavenumber of 1129 cm−1 to 1139 cm−1. The intensity of the base peak and the intensity of the first peak differ by −0.05 to +0.05. According to an embodiment, a polyester resin having a controlled degree of crystallization can be applied to a film to impart excellent heat resistance, mechanical properties, and the like to the film.

摘要： A polyester film according to an embodiment is characterized in that the shrinkage properties in a direction perpendicular to a main shrinkage direction are adjusted under certain heat treatment conditions, and thus further deformation of the polyester film can be suppressed even when the polyester film goes through a harsh retort process after being tightly adhered to a container by means of heat shrinkage. Thus, the polyester film according to the embodiment can be effectively applied, as a heat-shrinkable label or packing material, to containers of various products including retort food.
