This invention relates to a method of producing starch derived shaped articles and in particular, a method of producing films derived from high amylose starch. In the method, a hot melt is prepared by heating under pressure a composition comprising a high amylosic material, or a derivative thereof, and sufficient water to provide a homogeneous melt for subsequent extrusion as a shaped article. The hot melt is subjected to an atmospheric or subatmospheric pressure immediately prior to or during extrusion so as to remove water from the hot melt prior to the formation of the shaped article. Preferably, the high amylosic material is derived from Goodman Fielder Mills Pty. Limited maize hybrids 55/77 or 65/88. The starch derived films produced by the method are particularly suitable for use in oxygen barrier laminates and as biodegradable mulch films.
