Abstract

La presente invención es una película que tiene un grosor mayor a 100 micras que comprende de 10 a 100% en peso de un polímero de polietileno elaborado a través del proceso de a) seleccionar una resina de polietileno objetivo que tiene una densidad, tal como se determina de acuerdo con ASTM D792, dentro del rango de 0.90 glcm3 a 0.955 g/cm3, y un índice de derretimiento, tal como se determina de acuerdo con ASTM D1238 (2.16 kg, 190C), dentro del rango de 0.01 g/10 minutos a 10 g/10 minutos; b) hacer reaccionar el polietileno objetivo con un derivado de alcoxiamina en una cantidad menor a 900 partes de derivado por millón de partes en peso de la resina de polietileno total bajo condiciones suficientes para incrementar la resistencia al derretimiento de la resina de polietileno objetivo; y c) formar una película gruesa a partir de la resina objetivo modificada. Las películas de la presente invención incluyen las que pueden lograr una capacidad de procesamiento similar, a las que contienen un polietileno lineal no modificado a pesar de tener al menos el 10% menos de resinas LDPE en la formulación.
