Abstract

A blend composition comprising a first polyester and a second polyester. The first and second polyesters each comprises residues of terephthalic acid, neopentyl glycol (NPG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), and/or diethylene glycol (DEG). The first polyester comprises NPG, CHDM, and DEG in a combined amount that is less than the second polyester. The blend composition can be useful for producing a shrink film exhibiting high ultimate shrinkage (e.g., >65% at 95° C. for 10 seconds) and a high strain induced crystalline melting point (e.g., greater than 190° C.).
