1. A food packaging article for fresh uncured meat products having an interior surface and an exterior surface, the article comprising: a food contact layer comprising a myoglobin blooming agent, wherein the myoglobin blooming agent is selected from the group consisting of nitrosodisulfonates, transition metal/nitroso complexes, organic nitro compounds, organic nitroso compounds, O-nitrosylated compounds, S-nitrosylated compounds, nonoate compounds, furoxans, oxatriazole-5-imines, sydnonimines, oximes, nitrogen heterocycles; andan oxygen barrier layer;wherein the myoglobin blooming agent is present on the food contact layer surface in a concentration sufficient to produce a desirable surface coloration of the meat product and prevent undesirable extension of the color into the body of the meat product;wherein the concentration of myoglobin blooming agent is 0.900 mg/in2 or less. 2. The article of claim 1, wherein the myoglobin blooming agent is a nitrogen heterocycle selected from the group consisting of pyridines, pyrazines, pyrimidines, imidazoles, purines, triazines, and combinations thereof. 3. The article of claim 1, wherein the myoglobin blooming agent is a nitrogen heterocycle selected from the group consisting of nicotinic acids, salts or esters of nicotinic acid, nicotinamides, salts or esters of nicotinamide and combinations thereof. 4. The article of claim 1, wherein both the food contact layer and the oxygen barrier layer are the same layer. 5. The article of claim 1, wherein the article is a monolayer film, a multilayer film, a monolayer sheet, a multilayer sheet or a combination thereof. 6. The article of claim 1, wherein the article is a monolayer film or a multilayer film each having a thickness of less than 10 mil. 7.

The article of claim 19, wherein the polyester is selected from the group consisting of homopolymers or copolymers of polyethylene terephthalate, polylactic acid and blends thereof. 21. The article of claim 1, wherein at least one layer of the article is crosslinked. 22. The article of claim 14, wherein at least one layer of the article is irradiatively crosslinked. 23. The article of claim 1, further comprising at least one additional layer of a polyamide, a polyester, a polyethylene, a polypropylene, a polybutylene, a polystyrene, a polycarbonate, a cyclic olefin copolymer, a polyurethane, a polyacrylamide, an anhydride-modified polymer, an acrylate-modified polymer, or blends thereof. 24. The article of claim 1, wherein the food contact layer further comprises at least one of an antioxidant, a slip agent, an antiblock agent, a colorant, a flavorant, an odorant, an organoleptic agent, a coefficient of friction modifying agent, a lubricant, a surfactant, an encapsulating agent, an oxygen scavenger, a pH modifying agent, a film forming agent, an emulsifier, a polyphosphate, a humectant, a drying agent, an antimicrobial agent, a chelating agent, a binder, a starch, a polysaccharide or a combination thereof. 25. The article of claim 1, wherein the food contact layer comprises between about 0.10 weight % and about 5.0 weight % of the myoglobin blooming agent. 26. The article of claim 1, wherein the food contact layer comprises at least about 0.10 weight % and less than 2.0 weight % of the myoglobin blooming agent. 27. The article of claim 1, wherein the food contact layer comprises between about 0.75 weight % to about 1.75 weight % of the myoglobin blooming agent. 28. The article of claim 1, wherein the food contact layer has a food contact surface comprising between about 0.01 to about 10 μmole/inch2 of the myoglobin blooming agent. 29. The article of claim 1, wherein the food contact layer has a food contact surface comprising at least 0.1 mg/inch2 of the myoglobin blooming agent. 30. The article of claim 1, wherein the food contact layer has a food contact surface comprising less than 0.25 mg/inch2 of the myoglobin blooming agent. 31.
