Abstract: Multilayer biodegradable film particularly suitable for use in the manufacture of packaging, comprising at least one layer (A) comprising at least one aliphatic-aromatic biodegradable polyester blended with an aliphatic polyester having at least 70% in moles of succinic acid, and at least one layer (B) comprising a polymer composition comprising an aliphatic-aromatic polymer. The film has high mechanical properties, in particular a high elastic modulus, and appreciable optical transparency properties.
