HEAT-SHRINKABLE FILM COMPRISING COPOLYMER POLYESTER RESIN

摘要

There is provided a heat shrinkable film comprising a polyester based copolymer capable of having an excellent shrinkage rate and being heat shrunk at a low temperature. The heat shrinkable film according to an exemplary embodiment of the present invention includes a polyester based copolymer, wherein the polyester based copolymer includes: a dicarboxylic acid-derived residue including a residue derived from an aromatic dicarboxylic acid; and a diol-derived residue including a residue derived from 4-(hydroxymethyl)cyclohexylmethyl 4'-(hydroxymethyl)cyclohexane carboxylate represented by the following Chemical Formula 1 and a residue derived from 4,4-(oxybis(methylene)bis) cyclohexane methanol represented by the following Chemical Formula 2.
