摘要：
Disclosed is a shrink film containing a copolyester having a minimum crystallization half-time of at least 8.6 minutes and a polyester plasticizer having a weight-average molecular weight of 900 to 12,000 g/mol. The polyester plasticizer includes (i) a polyol component comprising residues of a polyol having 2 to 8 carbon atoms, and (ii) a diacid component comprising residues of a dicarboxylic acid having 4 to 12 carbon atoms.
