POLYESTER RESIN COMPOSITION

摘要

It is aimed to provide a resin composition which when formed into a film, is excellent in terms of tear strength and also excellent in terms of impact strength. The present invention relates to a polyester resin composition comprising: (A) a polyester resin containing 5 % by mole or more and not more than 86 % by mole of a succinic acid unit in the whole of an aliphatic dicarboxylic acid unit; (B) a polyester resin containing 5 % by mole or more and not more than 95 % by mole of an aromatic dicarboxylic acid unit in all of dicarboxylic acid units; and (C) a polyester resin containing an aliphatic oxycarboxylic acid, wherein the polyester resin composition contains from 10 to 89 % by weight of the polyester resin (A) and from 11 to 90 % by weight of the polyester resin (B) relative to a total sum of the polyester resin (A) and the polyester resin (B) and contains from 1 to 40 % by weight of the polyester resin (C) relative to a total sum of the polyester resin (A), the polyester resin (B), and the polyester resin (C).
