Beschreibung
Zusammenfassung:	The present invention relates to a sterilizable coextruded polymer composite tubular film for use as containers for solutions, suspensions, solids or mixtures for parenteral or enteral nutrition or tube feeding, optionally in a spatially separated arrangement of the contents, having a three-layered structure of the tubular film with the following layer sequence: a) polyamide 11 and/or polyetherblock amide; b) ethylene/vinyl alcohol copolymer with an ethylene content of 27 to 38 mole %; and c) homophase polypropylene copolymer which is suitable for forming the interior surface of the container. The invention further relates to a method for the preparation of such tubular film, and the use of the tubular film for the preparation of containers being sterilizable. L'invention porte sur un film tubulaire de composites de polymères à structure barrière stérilisable et coextrudés servant d'emballages pour des solutions, des suspensions, des solides, ou des mélanges à des fins de nutrition parentérale ou entérale ou de gavage intragastrique, éventuellement en séparant spatialement le contenu. Un tel film se compose de trois couches: (a) un polyamide 11 et/ou un amide à bloc de polyéther; (b) un copolymère d'éthylène/alcool vinylique contenant de 27 à 38 mole % d'éthylène; (c) un copolymère homophase de polypropylène convenant pour former la surface intérieure du tube. L'invention porte en outre sur un procédé de préparation dudit film, et sur son utilisation pour fabriquer des emballages stérilisables.
