Abstract: The invention relates to a foam layer which is produced from a biodegradable polyester mixture,comprising i) 70 to 5% by weight, based on the total weight of components i to ii, of at least one polyester made of aliphatic and aromatic dicarboxylic acids and aliphatic dihydroxy compounds and ii) 30 to 95% by weight, based on the total weight of components i to ii, of polylactide, and iii) 0.1 to 5% by weight, based on the total weight of components i to ii, of an epoxy group-containing copolymer made of styrene, acrylic ester and/or methacrylic ester, and iv) 0.5 to 15% by weight of additives; and v) 0 to 50% by weight of inorganic or organic fillers. The invention also relates to methods for producing said foam layer and to the use of the foam layer for producing molded articles. It finally relates to films and molded parts and to films that contain the foam layers according to the invention.

Abstract: The invention relates to biodegradable polyester mixtures comprising: between 5 and 80 wt. %, in relation to the total weight of the constituents i to ii, of at least one polyester based on aliphatic and aromatic dicarboxylic acids and aliphatic dihydroxy compounds (constituent i); between 20 and 95 wt. %, in relation to the total weight of the constituents i to ii, of at least one renewable raw material (constituent ii); and between 0.1 and 15 wt. %, in relation to the total weight of the constituents i to ii, of a constituent iii that is suitable for forming covalent bonds both with constituent i and with constituent ii. The invention also relates to methods for producing biodegradable polyester mixtures, the use of biodegradable polyester mixtures for producing blends, moulded parts, films or fibres, in addition to blends, moulded parts, films or fibres comprising biodegradable polyester mixtures.
