Abstract

SE DESCRIBE UNA PELICULA MULTICAPA COEXTRUSIONADA, TRANSPARENTE, SELLABLE EN AMBAS CARAS CON UNA CAPA BASE ESENCIALMENTE DE POLIMEROS DE PROPILENO Y CON CAPAS EXTERIORES ESENCIALMENTE DE POLIMEROS DE OLEFINAS SELLABLES. EL POLIMERO DE PROPILENO DE LA CAPA BASE ESTA DEGRADADO PEROXIDICAMENTE Y SU FACTOR A DE DEGRADACION SE HALLA ENTRE 3 Y 10. EL POLIMERO DE OLEFINAS SELLABLE DE LAS CAPAS EXTERIORES ES UN COPOLIMERIZADO DE ETILENO-PROPILENO CON UN CONTENIDO EN ETILENO DEL 2 AL 8% EN PESO, QUE TAMBIEN ESTA DEGRADADO PEROXIDICAMENTE. SU FACTOR DE DEGRADACION A SE HALLA ENTRE 3 Y 15.
