Resumen
La creciente demanda y el uso irresponsable en envasado alimentario de materiales plásticos
convencionales procedentes del petróleo está empeorando el problema medioambiental, ya que una
buena parte de la fabricación mundial de plástico va destinado a este fin. La sociedad, cada vez más
preocupada por el estado del planeta, exige soluciones que la ciencia respalda con la investigación de
nuevos materiales poliméricos, con base biodegradable, que cumplen características similares a sus
homólogos tradicionales, y que han sido reforzados con agentes inorgánicos naturales para optimizar
sus prestaciones técnicas y hacerlos adecuados para su uso en alimentación. En este trabajo se hace
una revisión de los estudios más relevantes sobre nanocompuestos de Mt/PLA, que confirman todas
las ventajas que pueden presentar en el ámbito del envasado alimentario.
The proliferation in demand and the misuse in food packaging of conventional plastic materials from petroleum is worsening the environmental problem, since a significant portion of the global plastic manufacturing is destined to this purpose. The society, more concerned every day with the state of the planet, demands solutions that science supports with the investigation of new polymeric materials, with a biodegradable base, that meet similar characteristics to their traditional equivalents. This new materials can be reinforced with natural inorganic agents to optimize their technical properties and make them suitable for use in contact with food. This work reviews the most relevant studies on Mt/PLA nanocomposites, which confirm all the advantages that they can present in the food packaging industry.
