Abstract

Se hacen películas y bolsas de polietileno de modulo mediano con un mejor funcionamiento de resistencia al desgarre para aplicaciones de empaque de trabajo pesado y usos de llenado en caliente. Las composiciones de película contienen polietileno lineal de alto peso molecular y un interpolímero de etileno/a-olefina lineal. La película es de cuando menos aproximadamente 31 micras de espesor, y se caracteriza por tener una densidad calculada de la película en la escala de 0.923 a 0.95 gramos/centímetro cubico (g/cc), y típicamente tiene una resistencia al desgarre o resistencia al impacto cuando menos el 30 por ciento mayor que la película de polietileno industrial actual. La película novedosa tiene una estabilidad dimensional y propiedades de resistencia superiores que permiten bajar el calibre de una manera significativa en relacion con las películas industriales utilizadas como sobreenvolturas, camisas y bolsas de trabajo pesado.
