Abstract
This application disclose an airtight film including a plastic base layer; a ceramic sealing layer formed on the plastic base layer; and a polymer sealing layer. The polymer sealing layer includes many polymer molecules chemically bonding to the ceramic sealing layer as a result of polymerization reactions of at least one monomer on the ceramic sealing layer as opposed to from coating of a pre-polymerized polymer composition on the ceramic sealing layer.

1-17. (canceled)
A laminate device comprising:
- a plastic base layer;
- a metal layer formed over the plastic base layer;
- and
- a polymer sealing layer formed on the metal layer without an adhesive layer interposed between the metal layer and the polymer sealing layer,
- wherein the polymer sealing layer comprises polymer molecules attached to the metal layer by covalent bonding as a result of polymerization reactions of at least one monomer on the metal layer as opposed to from coating of a pre-polymerized polymer composition on the metal layer,
- wherein the metal layer comprises holes and defects therein,
- wherein at least part of the polymer molecules bonds to inner surfaces of at least part of the holes and defects of the metal layer,
- wherein the polymer sealing layer does not comprise a binder, and there is no adhesive material bonding the metal layer and the polymer sealing layer therebetween,
- wherein the airtight film has a water vapor transmission (WVT) rate from about 1×10−6 μm2/day to about 1 g/m2/day.
