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.).

Crystallizable shrinkable films and thermoformable sheets made from resins blends

An oriented film or a shrink film comprising a polyester composition which comprises at least one polyester which comprises: a dicarboxylic acid component comprising: about 90 to about 100 mole % of terephthalic acid residues; about 0 to about 10 mole % of aromatic and/or aliphatic dicarboxylic acid residues having up to 20 carbon atoms; and a glycol component comprising: about 10 to about 29 mole % 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and about 71 to about 90 mole % ethylene glycol residues; and optionally, diethylene glycol residues; wherein the total mole % of the dicarboxylic acid component is 100 mole %, and wherein the total mole % of the glycol component is 100 mole %; wherein the inherent viscosity of the polyester is from 0.50 to 0.8 dL/g.
