Beschreibung
Zusammenfassung:	Insulating glazing unit comprises at least one spacer (15) for spacing glass sheets (10) in a frame (12). The spacer is applied with a barrier film (20) at least on the side facing against the frame. The barrier film is a composite film, which comprises an adhesive- or a sealing layer as the inner layer directed on the side facing against the spacer, and a blocking layer comprising oriented ethylene vinyl alcohol directed on the side facing against the frame, and an outer thin adhesive layer made of metal or metal oxide directed against the frame. An independent claim is also included for producing the barrier film for the insulating glazing unit, comprising producing composite film as the barrier film, which has outer adhesive- or sealing layer as the inner layer on one side, blocking layer made of oriented ethylene vinyl alcohol laminated on the barrier film, and thin adhesive layer made of metal or metal oxide on the other outer side of the composite film.
