Abstract

Una película que comprende una mezcla de (i) un polietileno de baja densidad lineal y (ii) una mezcla in-situ de copolímeros de etileno y una o más olefinas que tienen de 3 a 8 átomos de carbono, en donde (a) la relacion en peso del componente (i) con respecto al componente (ii) está en la escala de aproximadamente 0.01:1 a aproximadamente 6:1; (b) la mezcla se ha extruído bajo condiciones de extrusion, a un régimen de extrusion en la escala de aproximadamente 6 a aproximadamente 20 libras por hora pulgada de circunferencia de la matriz y a un espacio libre de matriz en la escala de aproximadamente 0.020 a aproximadamente 0.075 pulgadas; y (c) la película no exhibe esencialmente fractura a la fusion.
