A fully degradable and a compostable polyester based blend that is free from non- degradable organic or inorganic additives such as nucleating agents and the like. The thermal properties of the present blend are configured for optimised flow rate during process moulding via a 'flow rate enhancing component' being a relative low molecular weight biodegradable polyester. The blend also provides a resultant moulded article having the appropriate mechanical, physical and chemical properties including greatly improved toughness over existing PLA based blends. This is achieved by incorporating a 'toughening component' within the blend being a relatively high molecular weight component relative to the flow rate enhancing component.
