Abstract

Barrier assemblies including ultrathin barrier laminates and methods of making the barrier assemblies are provided. A barrier assembly includes a thermoplastic polymer skin layer having opposite first and second major surfaces, and a barrier stack coated on the first major surface of the thermoplastic polymer skin layer to form an integral protective layer having a thickness no greater than about 0.5 mil (about 12.7 microns). The removable carrier film has a major surface releasably attached to the second major surface of the thermoplastic polymer skin layer. In some cases, the removal of the carrier film results in ultrathin barrier laminates.
