Abstract

SE FABRICAN PELICULAS DE POLIETILENO DE MODULO MEDIO, CON RESISTENCIA MEJORADA AL DESGARRAMIENTO, PARA APLICACIONES DE EMBALAJE SUPERRESISTENTE, Y PARA LLENADO EN CALIENTE. LAS COMPOSICIONES DE PELICULA CONTIENEN POLIETILENO LINEAL DE ALTO PESO MOLECULAR, Y UN INTERPOLIMERO DE {AL}-OLEFINA/ETILENO SUSTANCIALMENTE LINEAL. LA PELICULA TIENE AL MENOS, APROXIMADAMENTE, 1.25 MILLONESIMAS DE PULGADA (31 MICRONES) DE GROSOR, UNA DENSIDAD DE PELICULA EN EL RANGO DE 0.293 A 0.95 GRAMOS/CENTIMETRO CUBICO (GR/CC), Y, TIPICAMENTE, PRESENTA UNA RESISTENCIA AL DESGARRAMIENTO, O RESISTENCIA AL IMPACTO, AL MENOS UN 30 POR CIENTO MAS ELEVADA QUE LA PELICULA DE POLIETILENO INDUSTRIAL ACTUAL. LA NUEVA PELICULA TIENE UNA BUENA ESTABILIDAD DIMENSIONAL, Y PROPIEDADES DE RESISTENCIA, LO CUAL PERMITE UNA REDUCCION APRECIABLE DEL CALIBRE.
