A method for producing a low-pressure thin-walled heat exchanger and a low-pressure thin-walled heat exchanger are described. In the production process, a thin metal cover layer and a thin metal or plastic cover layer are sealed together. The seal is provided by means of a thin layer made of a sealable polymer in the form of a coating on one side of at least one cover layer, and/or by means of a separate intermediate layer made of a sealable polymer. The two cover layers are sealed together by means of the layer arranged therebetween made of the sealable polymer, forming a hollow space suitable for the passage of a heat exchange medium, which can be designed as a channel system. Such heat exchangers can be produced particularly affordably in this manner.

A method is described for producing a base material for moulding flanged caps for containers for holding pharmaceutical substances. A base material produced according to such a method and a flanged cap for such containers are also described. In a first embodiment of the method, a metal foil and a plastic film are provided, the plastic film is furnished on one side with a print, and the metal foil is laminated with the printed plastic film in such a manner that the film side furnished with the print is arranged as a reverse print adjacent to the metal foil. In a second embodiment, a metal foil is furnished with a print and a plastic layer is extruded onto the printed side of the metal foil. The flanged cap is produced from such a base material by stamping and deep drawing.
