Abstract
Se describe una película de espuma de múltiples capas con una blancura superficial perceptible mejorada que comprende aplicaciones de bloqueo de luz, señalización y embalaje general. En una realización, la película tiene una densidad aparente de menos de 0,962 gr/cm3, en donde más del 50 % de las células de la capa de espuma son células cerradas. En una realización, la película de espuma de múltiples capas tiene un espesor superior a 1 mil y una de las capas superficiales sólidas contiene pigmento blanco. En otra realización, la capa superficial blanca tiene un valor de blancura de capa superficial superior a 80 según ASTM E313-73, y un valor de tinte de capa superficial inferior a 1 según ASTM E313-73, y el valor de luminosidad (L*) de la capa superficial blanca de más de 90 en la dimensión CIE L*a*b* según ASTM E308. En una realización, la película tiene una superficie muy suave con un valor de lisura inferior a 25 en la configuración de la unidad de lisura Sheffield según TAPPI T 538.
