摘要： The invention relates to a thermoplastic composition comprising: at least one mixture of polyesters (A) including at least one polylactic acid (A1) and at least one aliphatic polyester (A2) or a semi-aliphatic polyester other than polymer (A1); at least one starch (B); at least one organic plasticiser (C) for starch. The composition is characterised in that: the weight percentage of (A1) in relation to the weight of (A1) and (A2), expressed as dry weight, varies between 2 and 70%, advantageously between 10 and 50%, preferably between 18 and 30%; at least 50% of the weight of the polylactic acid (A1) is formed by semi-crystalline polylactic acid; and in that the weight ratio of starch (B)/organic plasticiser (C), expressed as dry weight, varies between 90/10 and 40/60.
