A multilayer material useful for packaging is disclosed, comprising a foam core comprising compressed foamed starch and a facing layer bonded to a surface of the foam core. A method of making the multilayer material is also disclosed, comprising forming a core of foamed starch, compressing the foamed starch core and bonding a facing layer to a surface of the foamed starch core. Apparatus for making the multilayer material is also disclosed, comprising a first station for supplying foamed starch pieces to a transport surface, a second station, downstream of the first station, for applying a bonding agent to the surfaces of the foamed starch pieces, a compressor for compressing the foamed starch pieces downstream of the second station; and a bonder for bonding a facing layer to at least one surface of the compressed foamed starch.
