    Abstract: Disclosed is a biodegradable polyester mixture comprising 45 to 95 wt %, based on the total weight of polyester I and II, of a polyester I constructed from an aliphatic C9-C18 dicarboxylic acid or a C9-C18 dicarboxylic acid derivative; terephthalic acid or a terephthalic acid derivative; a C3-C6 diol; an at least trihydric alcohol; and a chain extender. The biodegradable polyester mixture further comprises 5 to 55 wt %, based on the total weight of polyester I and II, of a polyester II constructed from an aliphatic C4-C6 dicarboxylic acid or a C4-C6 dicarboxylic acid derivative; terephthalic acid or a terephthalic acid derivative; a C3-C6 diol; an at least trihydric alcohol; and a chain extender. The biodegradable polyester mixture further comprises 10 to 25 wt %, based on the total weight, of calcium carbonate; and 3 to 15 wt %, based on the total weight, of talc.
