Abstract

The present invention relates to an MDO heat-shrinkable film of a copolymer polyester having excellent thermal resistance. In particular, the present invention provides a copolymer polyester MDO (machine direction orientation) thermoresistant heat-shrinkable film that consists of a copolymer polyester resin including isosorbide and 1,4-cyclohexanedimethanol at an optimized content ratio as a diol component copolymerized with an acid component including terephthalic acid, and having a number average molecular weight of 18,000 g/mol or more, and can be used for labels, cap seals, direct packaging, etc. of various containers due to the high shrink initiation temperature.
