DESCRIZIONE
The present invention relates to a biodegradable polyester film comprising: i) 80 to 95% by weight, based on the total weight of components i to ii, of a biodegradable polyester based on aliphatic and aromatic dicarboxylic acids and an aliphatic dihydroxy compound; ii) from 5 to 20% by weight, based on the total weight of components i to ii, of polyhydroxyalkanoate; iii) 0 to 25% by weight, based on the total weight of components i to vi, of calcium carbonate; iv) 0 to 15 wt .-%, based on the total weight of components i to vi, talc; v) 0 to 30 wt .-%, based on the total weight of components i to vi, polylactic acid and / or starch; vi) 0 to 2% by weight, based on the total weight of components i to vi, of 2- (4,6-bis-biphenyl-4-yl-1,3,5-triazin-2-yl) -5- (2-ethyl- (n) -hexyloxy) phenol. Furthermore, the invention relates to the use of these polyester films, in particular for agricultural applications such as mulch films.
