Beschreibung
Zusammenfassung:	The invention provides a biodegradable oxygen absorbing plastic comprising a biodegradable substrate a sufficient concentration of reduced iron particles to adsorb oxygen in significant quantities and reduce the deformation temperature of the substrate substantially below the deformation temperature without iron particles present. La invención proporciona un plástico biodegradable absorbente de oxígeno, que comprende un substrato biodegradable que tiene una concentración suficiente de partículas de hierro reducidas, para adsorber oxígeno en cantidades significantes y reducir la temperatura de deformación del substrato substancialmente por debajo de la temperatura de deformación sin partículas de hierro presentes.
