CLAIMS

What is Claimed:

1. A container comprising a composite material comprising a polycarbonate substrate and at least one SiOx layer deposited onto the polycarbonate substrate at an interior surface of the container, wherein the composite material:

a. has an oxygen transmission rate of between about 10"6 cm3/m2 day bar and about 1 cm3/m2- day bar when measured in accordance with ISO 15105-2; b. exhibits a barrier improvement factor of greater than 1000 when compared to a substantially similar polycarbonate substrate that does not include the SiOx layer;

c. exhibits a transmission of greater than about 88 % at a 2.5 mm film thickness; d. exhibits a surface roughness substantially similar to the surface roughness of a substantially similar polycarbonate substrate that does not include the SiOx layer; and

e. exhibits chemical resistance to organic solvents.

2. The container of claim 1, wherein the composite material has a surface roughness of less than about 2 nm.

3. The container of any of claims 1-2, wherein the composite material has a haze of from about 0.01 % to about 0.6 %.

4. The container of any of claims 1-3, wherein the composite material is proximate the interior surface of the container.

5. The container of any of claims 1-4, wherein the composite material further comprises an adhesion-promoting layer to facilitate adhesion of a successive layer.

6. The container of any of claims 1-5, wherein the at least one SiOx layer is deposited onto the polycarbonate substrate by a microwave and radio frequency plasma- enhanced chemical vapor deposition process.

7. The container of claim 6, wherein the composite material exhibits a roughness profile having vertical deviations less than that of a substantially similar composite material formed from a low radio frequency plasma-enhanced chemical vapor deposition process.

8. The container of claim 6 or 7, wherein the at least one SiOx layer is deposited onto the polycarbonate substrate by a microwave and radio frequency plasma-enhanced chemical vapor deposition process in combination with an atomic layer deposition process.

9. The container of claim 8, wherein the composite material has an oxygen transmission rate between about 10"6 cm3/m2 day bar and about 10"2 cmVm2- day bar when measured in accordance with ISO 15105-2.

10. The container of any of claims 6-9, wherein the microwave and radio frequency plasma-enhanced chemical vapor deposition process comprises exposing polycarbonate substrate to a process gas comprising at least one of tetraethoxysilane (TEOS), tetramethoxysilane (TMOS), and hexamethyldisilazane (HMDS), hexamethyldisiloxane (HMDSO) in order to cause deposition of the at least one SiOx layer onto the polycarbonate substrate.

11. The container of any of claims 1-10, wherein the composite material has a bisphenol- A migration level of:

a. less than 600 ppb when exposed to a 3% aqueous acetic acid solution at 121 degrees Celsius (°C) for 30 minutes (min);

b. less than 600 ppb when exposed to a 3% aqueous acetic acid solution at 60 °C for 10 days; or

c. both a and b.

12. The container of any of claims 1-11, wherein the container is a cosmetic,

pharmaceutical or food storage container.

13. The container of any of claims 1-12, wherein the interior surface of the container contacts a cosmetic, pharmaceutical or food product.

14. The container of any of claims 1-12, wherein the interior surface of the container contacts a perfume composition.

15. The container of any of claims 1-12, wherein the interior surface of the container contacts a medicinal composition or a medicament.

16. A medicament container comprising a composite material comprising a polycarbonate substrate and at least one SiOx layer deposited onto the polycarbonate substrate at an interior surface of the container, wherein the composite material:

a. has an oxygen transmission rate of between about 10"6 cm3/m2 day bar and about 1 cm3/m2- day bar when measured in accordance with ISO 15105-2; b. exhibits a barrier improvement factor of greater than 1000 when compared to a substantially similar polycarbonate substrate that does not include the SiOx layer;

c. exhibits a transmission of greater than about 88 % at a 2.5 mm film thickness; d. exhibits a surface roughness substantially similar to the surface roughness of a substantially similar polycarbonate substrate that does not include the SiOx layer; and

e. exhibits chemical resistance to organic solvents.

17. The container of claim 16, wherein the composite material has a surface roughness of less than about 2 nm.
