Abstract

Esta invención describe composiciones mejoradas para la eliminación de oxígeno. Estos materiales, caracterizados por el bajo grado de cristalinidad y una temperatura de transición vítrea de -10°C, tienen velocidades de eliminación de oxígeno elevadas a bajas temperaturas. La composición comprende un hidrocarburo etilénicamente insaturado y un catalizador de metal de transición y puede incorporarse en varios tipos de capas. Es preferible que la composición se incorpore en capas de artículos de capas múltiples utilizados para el envasado o empacado de productos sensibles al oxígeno, tales como productos alimenticios.
