Abstract

La presente se refiere a materiales termoplásticos biodegradables hechos de mezclas de ésteres de almidon y glicoles de polialquileno con adiciones deácidos carboxilicos y ácidos oxicarboxílicos polibásicos, alifáticos, los cuales son mejorados con respecto a su estabilidad ante el agua, sus características mecánicas y sus propiedades de barrera, gracias a que se han mezclado las mezclas con policarbonatos alifáticos en niveles desde 5:95 a 95:5 con la adicion opcional de plastificantes y rellenos ecologicamente compatibles. Estos materiales pueden ser aprovechados para toda clase de mercancía que debe ser empaquetada en películas, en particular productos de tabaco, pero también jabon, servilletas de papel, artículos de tocador y similares. Además de la biodegradabilidad, se caracterizan estos materiales porque pueden ser alimentados a un proceso de reciclaje especial, y también a los procesos de reciclaje convencionales sin que ellos sean afectados adversamente.
