Patent ID: 7776020

Claim:
An absorbent article comprising a laminated outer cover, the laminated outer cover comprising a biodegradable stretched aliphatic-aromatic copolyester film, the film comprising filler particles, a polyfunctional branching agent, and a copolyester comprising from about 10 mole % to about 30 mole % of aromatic dicarboxylic acid or ester thereof, from about 20 mole % to about 40 mole % of aliphatic dicarboxylic acid or ester thereof, from about 30 mole % to about 60 mole % dihydric alcohol, and wherein the weight average molecular weight of the copolyester is from about 90,000 to about 160,000 Daltons, and wherein the number average molecular weight of the copolyester is from about 35,000 to about 70,000 Daltons, and wherein the glass transition temperature of the copolyester is less than about 0° C., wherein the filler particles are coated up to 2% by weight with a fatty acid, and wherein the fatty acid is behenic acid.
