ABSTRACT:
A process for fabrication of a composite film including two films, includes: depositing by evaporation in a vacuum at least one intermediate functional layer which is non-metallic and transparent, and which functions as at least one of a barrier layer or a bonding layer, onto at least one of the two films; and joining the two films under conditions effective to create a bond therebetween; wherein, when at least one intermediate functional layer is deposited onto each of the two films, these two films are joined together along the surfaces thereof which carry the deposited at least one intermediate functional layer, and when at least one intermediate functional layer is deposited onto only one film of the two films, the one film is joined to the other of the two films along the surface of the one film which carries the deposited at least one intermediate functional layer.
