Abstract

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.

First claim

What is claimed:

1. A method of packaging a sterilized product, the method comprising:
sterilizing a product;
enclosing the sterilized product in a first layer, the first layer being configured to be removed in a Grade A environment to expose the sterilized product;
substantially hermetically sealing the first layer to form a first sealed enclosure;
enclosing the first sealed enclosure in a second layer, the second layer being configured to be removed in a Grade B environment to expose the first sealed enclosure;
substantially hermetically sealing the second layer to form a second sealed enclosure;
enclosing the second sealed enclosure in a third layer, the third layer being configured to be removed in a Grade C environment to expose the second sealed enclosure;
substantially hermetically sealing the third layer to form a third sealed enclosure;
enclosing the third sealed enclosure in a fourth layer, the fourth layer being configured to be removed in a Grade D environment to expose the third sealed enclosure; and
substantially hermetically sealing the fourth layer to form a packaged product.

2. The method of claim 1 , wherein sterilizing the product comprises sterilizing the product by gamma irradiation.

3. The method of claim 1 , wherein the product is a printing medium.

4. The method of claim 1 , wherein the first layer, the second layer, the third layer and the fourth layer are formed of a plastic material.

5. The method of claim 4 , wherein the plastic material is a plastic bag.

6. The method of claim 1 , wherein substantially hermetically sealing the first layer, the second layer, the third layer, and the fourth layer comprises heat sealing the first layer, the second layer, the third layer, and the fourth layer.

7. The method of claim 1 , further comprising:
enclosing the packaged product in a container for shipping.

8. A method of packaging a sterilized product, the method comprising:
sterilizing a product;
enclosing the sterilized product in a first layer, the first layer being configured to be removed in a Grade B environment to expose the sterilized product;
substantially hermetically sealing the first layer to form a first sealed enclosure;
enclosing the first sealed enclosure in a second layer, the second layer being configured to be removed in a Grade C environment to expose the first sealed enclosure;
substantially hermetically sealing the second layer to form a second sealed enclosure;
enclosing the second sealed enclosure in a third layer, the third layer being configured to be removed in a Grade D environment to expose the second sealed enclosure;
substantially hermetically sealing the third layer to form a third sealed enclosure;
enclosing the third sealed enclosure in a fourth layer, the fourth layer being configured to be removed near the Grade D environment to expose the third sealed enclosure; and
substantially hermetically sealing the fourth layer to form a packaged product.

9. The method of claim 8 , wherein sterilizing the product comprises sterilizing the product by gamma irradiation.

10. The method of claim 8 , wherein the product is a printing medium.

11. The method of claim 8 , wherein the first layer, the second layer, the third layer and the fourth layer are formed of a plastic material.

12. The method of claim 11 , wherein the plastic material is a plastic bag.

13. The method of claim 8 , wherein substantially hermetically sealing the first layer, the second layer, the third layer, and the fourth layer comprises heat sealing the first layer, the second layer, the third layer, and the fourth layer.

14. The method of claim 8 , further comprising:
enclosing the packaged product in a container for shipping.

15. A packaged sterilized product, comprising:
a sterilized product;
a first layer, substantially hermetically sealed, enclosing the sterilized product to form a first sealed enclosure, the first layer being configured to be removed in a Grade B environment to expose the sterilized product;
a second layer, substantially hermetically sealed, enclosing the first sealed enclosure to form a second sealed enclosure, the second layer being configured to be removed in a Grade C environment to expose the first sealed enclosure;
a third layer, substantially hermetically sealed, enclosing the second sealed enclosure to form a third sealed enclosure, the third layer being configured to be removed in a Grade D environment to expose the second sealed enclosure;
a fourth layer, substantially hermetically sealed, enclosing the third layer to form the packaged product, the fourth layer being configured to be removed near the Grade D environment to expose the third sealed enclosure.

16. The product of claim 15 , wherein the product is sterilized by gamma irradiation.

17. The product of claim 15 , wherein the product is a printing medium.

18. The product of claim 15 , wherein the first layer, the second layer, the third layer and the fourth layer are formed of a plastic material.

19. The product of claim 18 , wherein the plastic material is a plastic bag.

20. A packaged sterilized product, comprising:
a sterilized product;
a first layer, substantially hermetically sealed, enclosing the sterilized product to form a first sealed enclosure, the first layer being configured to be removed in a Grade A environment to expose the sterilized product;
a second layer, substantially hermetically sealed, enclosing the first sealed enclosure to form a second sealed enclosure, the second layer being configured to be removed in a Grade B environment to expose the first sealed enclosure;
a third layer, substantially hermetically sealed, enclosing the second sealed enclosure to form a third sealed enclosure, the third layer being configured to be removed in a Grade C environment to expose the second sealed enclosure;
a fourth layer, substantially hermetically sealed, enclosing the third layer to form the packaged product, the fourth layer being configured to be removed in a Grade D environment to expose the third sealed enclosure.

21. The product of claim 20 , wherein the first layer, the second layer, the third layer, and the fourth layer are substantially hermetically sealed by heat sealing.

22. The product of claim 20 , wherein the product is sterilized by gamma irradiation.

23. The product of claim 20 , wherein the product is a printing medium.

24. The product of claim 20 , wherein the first layer, the second layer, the third layer and the fourth layer are formed of a plastic material.

25. The product of claim 24 , wherein the plastic material is a plastic bag.

26. The product of claim 20 , wherein the first layer, the second layer, the third layer, and the fourth layer are substantially hermetically sealed by heat sealing.
