Abstract

Método para preparar películas de poliolefinas orientadas en donde las condiciones de orientación y de estiramiento están definidas para maximizarlas respuestas a la contracción sin restricciones de la película. Se refiere asimismo aestructu ras de películas de contracción así como a estructuras depelículas de contracción hechas por un método novedoso, en el que cada caso la película de contracción comprende como capa de control de contracción, almenos un interpolímero deetileno homogé neamente ramificado que presenta una densidad de polímero inferior a 0.91 g/cc. Las estructuras de películas puedenser empleadas en usos industriales tales como el envasamiento de carne con barrera y de artículos de papel.Method for preparing oriented polyolefin films where the orientation and stretching conditions are defined to maximize the unrestricted shrinkage responses of the film. It also relates to shrink film structures as well as shrink film structures made by a novel method, in which each case the shrink film comprises as shrinkage control layer at least one homogeneously branched ethylene interpolymer having a density of polymer less than 0.91 g / cc. Film structures can be used in industrial uses such as barrier meat packaging and paper goods packaging.
