Abstract
Esta invención se refiere generalmente a películas o láminas multicapa coextrudidas a base de copolímero de etileno\a-olefina o polietileno -rígidas o flexibles- para termoformarse en envases con forma tales como envases para envasado. Entre otros, las películas rígidas tienen propiedades de barrera, dureza y capacidad de quebrado mejoradas. Particularmente, las películas de la presente invención comprenden una o más pilas de capas de polipropileno. En una modalidad, las capas de polipropileno en la pila se proporcionan de tal manera que cualesquiera dos capas adyacentes tengan microestructuras diferentes que proporcionen una interfaz o interfase entre las dos capas con microestructuras y/o cristalinidad probablemente diferentes. La estructura general de pila de polipropileno ayuda a interrumpir el transporte de oxígeno, proporcionando así un laminado o estructura, por ejemplo, una película o lámina rígida, con propiedades de barrera mejorada al oxígeno. La invención también se relaciona con un proceso para preparar artículos con forma, tales como envases de tales películas, y a tales artículos formados - rígidos o flexibles - tanto llenos como no llenos.
