HDPE nanocomposite is made by mixing HDPE with organoclay. Such HDPE nanocomposite contains concentrations of organoclay less than 4 weight percent. Unexpectedly, using less organoclay than that conventionally recommended, results in superior oxygen and water vapor transmission rates for HDPE compounds. The HDPE nanocomposite is useful for packaging films and containers for food or other perishables.

What is claimed is: 1. A method of using organoclay to improve barrier properties of high density poly(ethylene), comprising the step of mixing organoclay into the high density poly(ethylene) to form a nano-high density poly(ethylene) compound, wherein the amount of organoclay is greater than 0 and less than about 4 weight percent. 2. The method of claim 1, wherein the high density poly(ethylene) has a specific gravity above 0.935. 3. The method of claim 1, wherein the high density poly(ethylene) is a grade and quality approved for use with food or other perishables. 4. The method of claim 1, wherein the organoclay is a smectite clay. 5. The method of claim 1, wherein the organoclay is a montmorillonite clay. 6. The method of claim 1, wherein the organoclay is intercalated with an organic intercalant. 7. The method of claim 1, further comprising the step of forming the compound into a film, and wherein the film has a lower water vapor transmission rate and a lower oxygen permeability than if the compound were to contain more than about four weight percent of organoclay. 8. The method of claim 1, wherein the amount of organoclay is greater than 0 and less than about 3 weight percent of the compound. 9. The method of claim 1, further comprising mixing an additive into the compound in a sufficient amount to obtain a desired processing or performance property, wherein the additive is selected from the group consisting of adhesion promoters; antibacterial biocides, fungicidal biocides, mildewcides, anti-fogging agents; anti-static agents; bonding, blowing and foaming agents; dispersants; fillers; extenders; fire retardants; flame retardants; smoke suppressants; impact modifiers; initiators; lubricants: micas; pigments; colorants; dyes; plasticizers; processing aids; release agents; silanes, titanates and zirconates; slip agents; anti-blocking agents; stabilizers; stearates; ultraviolet light absorbers; viscosity regulators; waxes; and combinations of them. 10. The method of claim 1, further comprising mixing another polymer into the compound, wherein the compound is selected from the group consisting of polyolefins, polyimides, polycarbonates, polyesters, polysulfones, polylactones, polyacetals, acrylonitrile-butadiene-styrene resins (ABS), polyphenyleneoxide (PPO), polyphenylene sulfide (PPS), polystyrene, styrene-acrylonitrile resins (SAN), styrene maleic anhydride resins (SMA), aromatic polyketones (PEEK, PED, and PEKK) and mixtures thereof. 11. An article formed from a compound comprising high density poly(ethylene) and greater than 0 and less than about four weight percent of organoclay, wherein the article has a lower water vapor transmission rate and a lower oxygen permeability than if the compound were to contain more than about four weight percent of organoclay. 12. The article of claim 11, wherein the high density poly(ethylene) has a specific gravity above 0.935. 13. The article of claim 11, wherein the high density poly(ethylene) is a grade and quality approved for use with food or other perishables. 14. The article of claim 11, wherein the organoclay is a smectite clay. 15. The article of claim 11, wherein the organoclay is a montmorillonite clay. 16. The article of claim 11, wherein the organoclay is intercalated with an organic intercalant. 17. The article of claim 11, wherein the amount of organoclay is less than about 3 weight percent of the compound. 18. The article of claim 11, further comprising mixing an additive into the compound in a sufficient amount to obtain a desired processing or performance property, wherein the additive is selected from the group consisting of adhesion promoters; antibacterial biocides, fungicidal biocides, mildewcides, anti-fogging agents; anti-static agents; bonding, blowing and foaming agents; dispersants; fillers; extenders; fire retardants; flame retardants; smoke suppressants; impact modifiers; initiators; lubricants; micas; pigments; colorants; dyes; plasticizers; processing aids; release agents; silanes, titanates and zirconates; slip agents; anti-blocking agents; stabilizers; stearates; ultraviolet light absorbers; viscosity regulators; waxes; and combinations of them. 19. The article of claim 11, further comprising another polymer mixed into the compound, wherein the compound is selected from the group consisting of polyolefins, polyimides, polycarbonates, polyesters, polysulfones, polylactones, polyacetals, acrylonitrile-butadiene-styrene resins (ABS), polyphenyleneoxide (PPO), polyphenylene sulfide (PPS), polystyrene, styrene-acrylonitrile resins (SAN), styrene maleic anhydride resins (SMA), aromatic polyketones (PEEK, PED, and PEKK) and mixtures thereof. 20. The article of claim 11, wherein the article is a film.
