Abstract

Una película para estirar con tres o más capas, en donde: A) al menos una capa comprende un polietileno caracterizado por tener: i) una densidad de 0,9 g/cm3 a 0,96 g/cm3; ii) un índice de fluidez de 0,5 5 g/10 minutos a 10 g/10 minutos, medido según la norma ASTM D- 1238, condición 190 °C/2,16 kg; y iii) una distribución de peso molecular de 2,5 a 4,5; y iv) un Índice de Amplitud de Distribución de Composición (CDBI) mayor del 50 por ciento, en donde CBDI se define como el porcentaje en peso de las moléculas del polímero con un contenido en comonómero dentro del 50 por ciento del contenido molar total medio de comonómero, y B) en donde al menos una capa no superficial comprende al menos un polímero de propileno; y C) en donde la película para estirar se caracteriza por tener un estiramiento en el punto de rotura de al menos 200 %, una resistencia al impacto por Punzón A de al menos 16,9 g/μ30 g/mil) medido según la norma ASTM D-1709 y una CF del 5 % o menos, en donde CF se define como la relación del porcentaje de estiramiento en el punto de rotura menos el porcentaje de estiramiento en el punto de fallo catastrófico dividido por el porcentaje de estiramiento en el punto de rotura.
