A METHOD OF PRODUCING A GAS BARRIER POLYMER FOIL AND A GAS BARRIER POLYMER FOIL

摘要

The invention relates to polymer foil comprising at least one polymer layer coated with a barrier glass coating of an oxide composition, wherein said oxide composition comprises the element Si in the form of an oxide network, the oxide composition preferably comprises Si and at least one other element X in an oxide network. The oxide network may preferably be applied using plasma. The foil may be a multi-layered foil comprising a plurality of layers. The foil has good barrier properties.
