Abstract
The present invention describes package units for medical purposes, in particular for receiving and/or storing sterilizable preparations for parenteral uses or dialysis solutions, comprising a container having at least one discharge spout and consisting of polyamide 66 or a laminate of polyamide 66 sheet and polyolefin sheet, the polyolefin sheet being disposed on the side facing the liquid to be stored and the sheet of polyamide 66 being disposed on the outside and the two sheets being bonded together in usual manner by means of an adhesive. The package units may further comprise an inner container or an outer container. The package unit is made in that a container having at least one discharge spout is made from polyamide 66 or the aforementioned laminate, said container filled with the liquid to be stored, then sealed and sterilized and possibly subsequently surrounded after cooling and drying with an outer container of polymeric material. Package units according to the invention may also be made in that from a polymeric material an inner container having at least one discharge spout is made, said container filled with the liquid to be stored, sealed, then surrounded with an outer container of polyamide 66 or a laminate of polyamide 66 sheet and polyolefin sheet, the polyolefin sheet being disposed at the side of the laminate facing the inner container and the sheet of polyamide 66 of the laminate representing the outer sheet, and thereafter sterilized.
