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. |
