Abstract

A film that is formed from a biodegradable polymer blend of different aliphatic-aromatic copolyesters is provided. More specifically, the blend contains a first copolyester formed from a terephthalic acid monomer. The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-)terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer.
