Abstract: The present invention relates to an injection molded article comprising: i) 27% to 87% by weight based on the total weight of the components i to iv of a polyester constructed from aliphatic dicarboxylic acids and aliphatic diols; ii) 3% to 15% by weight based on the total weight of the components i to iv of an aliphatic-aromatic polyester comprising: ii-a) 30 to 70 mol % based on the components ii-a to ii-b of a C6-C18-dicarboxylic acid; ii-b) 30 to 70 mol % based on the components ii-a to ii-b of terephthalic acid; ii-c) 99 to 100 mol % based on the components ii-a to ii-b of 1,3-propanediol or 1,4-butanediol; ii-d) 0% to 1% by weight based on the components ii-a to ii-c of a chain extender and/or branching agent; iii) 0% to 35% by weight based on the total weight of the components i to iv of polylactic acid; iv) 10% to 35% by weight based on the total weight of the components i to iv of at least one surface-modified silicate selected from the group consisting of: kaolin, muscovite, montmorillonite, talc and wollastonite.
