Plastic film with good barrier effect after a sterilisation treatment

The plastic film comprises a barrier layer, which is made of amorphous hydrogenated carbon produced by plasma-enhanced chemical vapor deposition and doped with nitrogen, a second barrier layer, which is made of metal, metal oxide such as silicon oxide or metal nitride and arranged on the first barri...

Beschreibung
Zusammenfassung:	The plastic film comprises a barrier layer, which is made of amorphous hydrogenated carbon produced by plasma-enhanced chemical vapor deposition and doped with nitrogen, a second barrier layer, which is made of metal, metal oxide such as silicon oxide or metal nitride and arranged on the first barrier layer, and a further barrier layer arranged between the first and the second barrier layers as intermediate layer. The further barrier layer is made of amorphous hydrogenated carbon and doped with nitrogen and silicon. An independent claim is included for a method for the production of plastic film. Ein Kunststoffflim für Verpackungezwecke, mit guter Durchtrittssperrwirkung gegenüber Gasen, Wasserdampf und Aromastoffen nach einer Sterilisierbehandlung, weist eine durch Plasma unterstützte chemische Gasphasenabscheidung (PECVD) erzeugte Sperrschicht aus amorphem hydriertem und mit Stickstoff (N) dotiertem Kohlenstoff (a-C:N:H) auf.
