Abstract

La presente invención se refiere a una película retráctil a base de poliéster que tiene una excelente resistencia al impacto predeterminada y que tiene una relación de encogimiento uniforme cerca de la temperatura de encogimiento. Se describe una película retráctil a base de poliéster que satisface las siguientes configuraciones (a) a (c): (a) la fuerza de resistencia al impacto antes del encogimiento, medida por un probador de impacto de película, se designa como A1, y está comprendida entre 20 y 60 J/mm; (b) cuando la fuerza de resistencia al impacto medida por un probador de impacto de película después de haber sido encogida un 10% en agua caliente a 80 °C se designa como A2, el valor numérico representado por A2/A1 x 100 está comprendido dentro del intervalo de 60% y 110%; y (c) cuando la relación de encogimiento en las condiciones de 80 °C y 10 segundos se designa como B1, y la relación de encogimiento en las condiciones de 90 °C y 10 segundos se designa como B2, el valor numérico representado por B1/B2 x 100 está dentro de 70% a 90%.
