DESCRIZIONE
The invention relates to a biodegradable polyester film, comprising: i) 80 to 95 wgt.-%, based on the total weight of the components i to ii, of a biodegradable polyester based on aliphatic and aromatic dicarboxylic acids and an aliphatic dihydroxy compound; ii) 5 to 20 wgt.-%, based on the total weight of the components i to ii, of polyhdroxyalkanoate; iii) 10 to 25 wgt.-%, based on the total weight of components i to vi, of calcium carbonate; iv) 3 to 15 wgt.-%, based on the total weight of components i to vi, of talc; v) 0 to 30 wgt.-%, based on the total weight of the components i to vi, of polyactic acid and/or starch; and vi) 0 to 2 wgt.-%, based on the total weight of the components i to vi, of 2-(4,6-Bis-biphenyl-4-yl-1,3,5-triazin-2-yl)-5-(2-ethyl-(n)-hexyloxy)phenol. The invention further relates to the use of said polyester films, in particular for agricultural applications such as mulching films.
