Abstract
Disclosed is a heat-shrinkable polyester film having a heat shrinkage initiation temperature of 60° C. or lower, a glass transition temperature (Tg) of 77° C. or lower and a heat shrinkage rate of 2% or more at 60° C. which has relatively low glass transition temperature and heat shrinkage initiation temperature, and thus can be useful as a label for a high-density polyethylene (HDPE) container and the like.
