Abstract: The invention relates to a biodegradable polyester film, containing: i) 75 to 100 wt %, relative to the total weight of components i to ii, of a biodegradable polyester based on aliphatic and/or aromatic dicarboxylic acids and an aliphatic dihydroxy compound; ii) 0 to 25 wt %, relative to the total weight of components i to ii, of polylactic acid; iii) 10 to 25 wt %, relative to the total weight of components i to v, of calcium carbonate; iv) 3 to 15 wt %, relative to the total weight of components i to v, of talc; v) 0 to 1 wt %, relative to the total weight of components i to v, of a copolymer containing epoxide groups and based on styrene, acrylic acid ester, and/or methacrylic acid ester; vi) 0 to 2 wt %, relative to the total weight of components i to v, of 2-(4,6-bis-biphenyl-4-yl-1,3,5-triazin-2-yl)-5-(2-ethyl-(n)-hexyloxy)phenol.
