Abstract

An anti-microbial packaging includes an innermost decontamination layer defining an inside and exposed surface of the packaging against which items in the packaging would contact. A fiber substrate layer is fixed to the innermost decontamination layer which itself is a metal or a metallic-alloy layer.

Claims (40)

1 . An anti-microbial packaging, comprising:

an innermost decontamination layer having a thickness between 300-400 angstroms, said innermost decontamination layer defining an inside and exposed surface of said packaging against which items in said packaging would contact;

a paper substrate layer fixed to said innermost decontamination layer;

a metallic foil layer on an opposing side of said paper substrate layer from said innermost decontamination layer;

a plastic or polymer film layer disposed between said innermost decontamination layer and said paper substrate layer; and

a polymer layer covering said metallic foil layer, said polymer layer being a non-porous material;

wherein each of said innermost decontamination layer, said paper substrate layer, said metallic foil layer, said plastic or polymer film layer, and said polymer layer have a length and width that are coextensive with one another;

wherein said innermost decontamination layer is comprised of one of a metal and a metallic-alloy;

wherein said innermost decontamination layer forms an entirety of said inside and exposed surface of said packaging;

and

wherein said paper substrate layer is disposed between said innermost decontamination layer and said metallic foil layer.

2 . The anti-microbial packaging according to claim 1 , wherein:

said metal and said metallic-alloy contains copper.

3 . The anti-microbial packaging according to claim 1 , wherein:

said metal and said metallic-alloy that form said innermost decontamination layer are deposited on said paper substrate layer.

4 . The anti-microbial packaging according to claim 3 , wherein:

said metallic foil layer contains one of aluminum and copper.

5 . The anti-microbial packaging according to claim 1 , wherein:

said paper substrate layer is impregnated with an anti-microbial agent.

6 . The anti-microbial packaging according to claim 1 , wherein:

said metal and said metallic-alloy that form said innermost decontamination layer contains silver.

7 . The anti-microbial packaging according to claim 1 , wherein:

said metallic foil layer supports a holographic image thereon.

8 . The anti-microbial packaging according to claim 1 , wherein:

said polymer layer forms an outer, exposed surface of the anti-microbial packaging such that said metallic foil layer is viewable through said polymer layer from outside said anti-microbial packaging.

9 . An anti-microbial packaging, comprising:

an innermost decontamination layer having a thickness between 300-400 angstroms, said innermost decontamination layer defining an inside and exposed surface of said packaging against which items in said packaging would contact;

a substrate layer fixed to said innermost decontamination layer;

a metallic foil layer fixed to an opposite side of the substrate layer from the innermost decontamination layer;

a polymer layer covering said metallic foil layer, said polymer layer being a non-porous material; and

a plastic or polymer film layer disposed between said innermost decontamination layer and said substrate layer;

wherein each of said innermost decontamination layer, said substrate layer, said metallic foil layer, said polymer layer, and said plastic or polymer film layer have a length and a width that are coextensive with one another;

wherein said innermost decontamination layer is comprised of copper;

wherein said innermost decontamination layer forms a substantial entirety of said inside and exposed surface of said packaging;

wherein said innermost decontamination layer is a separate and distinct layer from said substrate layer; and

wherein said plastic or polymer film layer is a separate and distinct layer from said innermost decontamination layer and said substrate layer.

10 . The anti-microbial packaging of claim 9 , wherein:

said metallic foil layer comprises at least one holographic image or pattern.

11 . The anti-microbial packaging of claim 10 , wherein:

said metallic foil layer comprises copper or a copper-containing alloy.
