摘要：
The invention relates to a mixture of biodegradable polyesters which includes an aromatic-aliphatic polyester (A), an aliphatic polyester (B) and a polylactic acid polymer (C) in which the concentration of A varies, with respect to (A+B) in the range between 40 and 70% by weight, and the concentration of C with respect of (A+B+C) is of between 6 and 30% by weight.
