Abstract

Una película térmicamente encogible con características de encogimiento mejoradas tiene un copolímero de etileno y acetato de vinilo con de nueve por ciento a veinte por ciento en peso de acetato de vinilo, con distribución de peso molecular limitada y un alto grado de ramificación de cadena corta. Una modalidad de capas múltiples incluye una primera capa de un copolímero de ácido, un copolímero de etileno y alfa-olefina, o mezclas de los dos; y una segunda capa de un copolímero de etileno y acetato de vinilo con de nueve por ciento a veinte por ciento en peso de acetato de vinilo, con distribución de peso molecular limitada y un alto grado de ramificación de cadena corta. Otra modalidad incluye una primera capa de un copolímero de ácido, un copolímero de etileno y alfa-olefina y mezcla de los mismos; una segunda capa de un copolímero de etileno y acetato de vinilo con un nueve por ciento a veinte por ciento en peso de acetato de vinilo, con distribución de peso molecular limitada y un alto grado de ramificación de cadena corta; una tercera capa de un copolímero de barrera; una cuarta capa de un copolímero de etileno y acetato de vinilo con de nueve a veinte por ciento de acetato de vinilo, con distribución de peso molecular limitada y un alto grado de ramificación de cadena corta; y una quinta capa de un copolímero de etileno y alfa-olefina.
