Aliphatic-aromatic polyesters, and articles made therefrom

An aliphatic-aromatic copolyester, comprising an acid component, a glycol component, and 0 to about 5.0 mole percent of a polyfunctional branching agent;

• wherein said acid component comprises:
• a. about 68.0 to 40.0 mole percent of an aromatic dicarboxylic acid component based on 100 mole percent total acid component;
• b. about 32.0 to 56.0 mole percent of sebacic acid, based on 100 mole percent total acid component
• c. no sulfonated component;
• and
• wherein said glycol component consists essentially of
• 1,3-propanediol and optionally
• b. 0 to 5.0 mole percent of a second glycol component, based on 100 mole percent total glycol component.
