Abstract

BURBUJAS CERRADAS DE ESPUMA PERFECCIONADAS, PARTICULARMENTE ADECUADAS PARA EMBALAJES QUE CONSTAN DE HEBRAS PARALELAS COALESCIDAS O PERFILES DE RESINA TERMOPLASTICA. CUANDO LA RESINA ES UNA OLEFINA NO AROMATICA, LA FUERZA DE SELLADO POR CALOR DE UNA PELICULA ES AL MENOS 30 NEWTONS/PULGADA (2,5 CM). PREFERENTEMENTE, LA RESINA ES UNA MEZCLA DE RESINA POLIMERICA DE OLEFINA Y UN COPOLIMERO DE ETILENO CON UNO O MAS COMONOMEROS COPOLIMERIZABLES DE PUNTO DE FUSION MAS BAJO QUE EL DE LA RESINA POLIMERICA DE OLEFINA. LA SECCION TRANSVERSAL DE LAS HEBRAS O PERFILES Y/O SU DISPOSICION ESPACIAL PERMITEN SU UNION POR LOS EXTREMOS PARA FORMAR HUECOS QUE DEFINEN UNA RED. LA RESINA PUEDE CONTENER HASTA UN 50% EN PESO DE UN AGENTE NUCLEANTE, PREFERENTEMENTE NEGRO DE CARBON. LAS HEBRAS Y PERFILES SON EXTRUIDOS A TRAVES DE UNA MATRIZ MULTIPERFORADA, ALGUNOS DE CUYOS ORIFICIOS SON TEMPORALMENTE DESBLOQUEADOS PARA PRODUCIR LA FORMA ESTRUCTURAL DESEADA.
