Abstract

Se hace una pelicula de polimero al mezclar bolas de almidon y de PVA juntas, y despues extruir de manera termoplastica la mezcla. La mezcla debe contener al menos 10% y preferentemente al menos 25% (en peso) de cada polimero, y la extrusion genera una pelicula homogenea que parece uniforme. Puede ser tan delgada como 20 (m. La pelicula resultante es facilmente biodegradable, soluble en agua o dispersable en agua, y tiene buenas propiedades fisicas. Este mismo proceso de extrusion por mezclado de bola, seguido por moldeo por inyeccion, puede utilizarse para formar otros objetos.
