Abstract

La presente invención proporciona películas recubiertas y paquetes formados a partir de tales películas. En un aspecto, una película parcialmente recubierta comprende (a) una película que tiene dos superficies externas, en donde una primera superficie externa es provista por una capa de película que comprende del 70 al 100 por ciento en peso de una poliolefina que tiene una densidad de 0.860 a 0.965 g/cm3; y (b) un recubrimiento en la primera superficie externa de la película que comprende poliuretano, en donde el recubrimiento cubre menos del 25 % del área superficial de la primera superficie externa de la película y en donde la porción recubierta de la película exhibe una rotura de Elmendorf en al menos una de la dirección de la máquina o dirección transversal que es al menos un 20 % menos que la rotura de Elmendorf de la porción no recubierta en la misma dirección, midiéndose la rotura de Elmendorf de acuerdo con la ASTM D1922.
