Abstract
Heat-shrinkable polyester films which exhibit a total light transmittance of 80% to 90% and a haze of 15% to 60%, both in a thickness of 50 &mgr;m and further exhibit a 45-degrees specular gloss of 70% or lower, so that they have frosted glass appearances without being printed or processed. Heat-shrinkable polyester films which exhibit a light transmittance of 0% to 20% at a wavelength of 380 nm and of 0% to 60% at a wavelength of 400 nm and further exhibit a haze of 15% or lower, so that they can prevent the contents of a vessel fitted therewith from being deteriorated by ultraviolet light and they have good shrinkage finish and particularly cause only rare occurrence of wrinkles, shrinkage spots, or other defects. These films are suitable for labels, particularly for labels of great product value.
