Abstract
The present invention relates to an MDO thermoresistant heat-shrinkable multilayer film of a copolymer polyester having excellent thermal resistance. In particular, the present invention provides an MDO thermoresistant heat-shrinkable multilayer film that includes multiple skin layers capable of improving thermal resistance formed on a substrate layer capable of providing high shrinkage, and simultaneously has excellent thermal resistance and high shrinkage properties through MD orientation instead of the conventional TD orientation method.
