Provided is a resin composition that is suitable for use in producing a film or sheet having high tear strength and is excellent in processability, mechanical properties, and biodegradability. The resin composition is a biodegradable polyester resin composition containing an aliphatic polyester (P3HA) having a repeating unit represented by the following general formula (1)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ[-CHR-CH 2 -CO-O-]€ƒ€ƒ€ƒ€ƒ€ƒ(1)
(wherein R is an alkyl group represented by C n H 2n+1 and n is an integer of 1 or more and 15 or less), polybutylene adipate terephthalate (PBAT), and hydrophilic silica (A), wherein a weight ratio of the aliphatic polyester (P3HA) to the polybutylene adipate terephthalate (PBAT) is 90/10 to 10/90, and an amount of the hydrophilic silica (A) contained is 2 to 30 parts by weight with respect to 100 parts by weight of a total amount of the aliphatic polyester (P3HA) and the polybutylene adipate terephthalate (PBAT) contained. |
