Abstract

Los materiales de película y en hojas, y artículos producidos de los mismos tales como sacos de bolsas, bandejas, etc. comprenden una o más capas de un copolímero de alfa-olefina/vinilo aromático homogéneo, de preferencia un copolimero de etileno/estireno. El copolímero de alfa-olefina/vinilo aromático tiene propiedades que pueden proporcionar características de un funcionamiento deseado tal como resistencia al impacto, capacidad de impresion, capacidad de sellado de radiofrecuencia, encogimiento libre, optica, alta permeabilidad, etc. El copolímero de alfa-olefina/vinilo aromático homogéneo puede estar presente en una película de monocapa, ya sea solo en una mezcla o puede incluirse en una o más capas de una película de capas multiples. Se incluye también un artículo termoformable de capas multiples que comprende una cinta continua que tiene una película de estos copolímeros de alfa-olefina/vinilo aromático.
