Abstract

Se provee un film de polietileno con un balance de propiedades mecánicas y físicas mejoradas y un método para producirlas. En un aspecto, el film incluye un módulo secante de 1% de más de 25.000 psi, una resistencia al impacto de dardo mayor que 500g/mil y una resistencia al desgarro longitudinal (MD) de más de 500g/mil. En un aspecto el método comprende unidades derivadas de etileno y un comonómero que reaccionan en presencia de un metaloceno a base de hafnio a una temperatura de 70sC a 90sC, una presión parcial de etileno de 120 psi a 260 psi, y una relación de comonómero a etileno desde 0,01 a 0,02 para producir un polímero a base de etileno. El método comprende además la extrusión del polímero a base de etileno en condiciones suficientes como para producir un film de polietileno que comprende un módulo secante de más de 25.000 psi, una resistencia al impacto de dardo de más de 500 g/mil, y una resistencia al desgarro longitudinal MD de más de 500 g/mil.
