Abstract
La presente invención se refiere a una película de polímero de etileno encogible con calor, caracterizada porque tiene un encogimiento térmico de área de cuando menos 20 por ciento a 90 grados C y una variación de espesor de no más de 20 por ciento, siendo la película de etileno encogible con calo una película biaxialmente estirada de un polímero de etileno que comrende por lo menos un copolímero lineal de etileno y -olefina en una relación d estiramiento de por lo menos 2 en cada una de las direcciones de máquina y transversal; indicando dicho polímero de etileno una curva de calorimetría por exploración diferencial (CED) en la cual el área endotérmica debajo de la temperatura inferior a la temperatura de fusión (la temperatura de pico endotérmico principal) del polímero de etileno, en 10 grados C, equivale a cuando menos el 55 por ciento del área total endotérmica.
