Abstract: The polyester compositions of the invention are useful in the manufacture of shrinkable films. The shrinkable films of the invention are comprised of polyester compositions comprising certain combinations of glycols and dicarboxylic acids in particular proportions which provide a lower level of shrinkage while having a melting temperature to accommodate modern sorting and recycling technologies.
