Document Type and Number:
WIPO Patent Application WO/2004/052968
Kind Code:
A1
Abstract:
A biodegradable polyester film formed from an aliphatic polyester copolymer which comprises (A) 0.02 to 30 mol% units of an aliphatic hydroxycarboxylic acid, (B) 35 to 49.99 mol% units of an aliphatic or alicyclic hydrocarbon diol, and (C) 35 to 49.99 mol% units of an aliphatic dicarboxylic acid and has a number-average molecular weight of 10,000 to 200,000. The film has either a Young's modulus in at least one direction of 0.5 to 3.5 GPa or a heat-sealing strength in at least one direction as measured in accordance with JIS Z 1707 of 20 to 80 N/15 mm-width.
