摘要
There is provided a composition for forming a heat shrinkable film capable of providing a heat shrinkable film capable of having an excellent shrinkage rate and being heat-shrunk at a low temperature. The composition for forming a heat shrinkable film includes a polyethylene terephthalate (PET) resin having an inherent viscosity of 0.50 to 1.2dl/g; and a polyester based copolymer including 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.展开▼
