The present invention relates to a film comprising at least one biodegradable layer (i) having an elastic modulus of more than 450 MPa, consisting of a mixture of polyhydroxyalkanoate constituting the continuous phase and aliphatic and/or aliphatic-aromatic polyester constituting the discontinuous phase, and at least one coating layer (ii) preferably capable of having barrier effects against gases and liquids. The surface of said layer (i) will have a root mean square roughness Sq of more than 10 nm and less than 45 nm, measured by atomic force microscopy (AFM). The film is particularly suitable for use in food packaging.
