Food package

Abstract

The invention regards a plastic comprising a level of detectable 8-Nonenal ranging from about 0 to about 400 ppt. Preferably, the plastic is substantially free of perceptible off flavor. Also, in one execution the plastic is used to form a package (e.g., a food and/or beverage bearing package). The package may be constructed of a monolayer of plastic material. Typically, about 20 to about 100% of the package comprises from about 0 to about 1900 ppt of 8-Nonenal. Preferably, the level of the 8-Nonenal of a stored food or beverage product stored in the package for 7 days at a temperature of 150° F. ranges from about 0 to about 400 ppt as measured in a grouping of representative packages with product therein.

What is claimed is:  
     
         1 . A plastic comprising a level of detectable 8-Nonenal ranging from about 0 to about 400 ppt.  
     
     
         2 . The plastic of  claim 1  wherein the plastic is substantially free of perceptible off flavor.  
     
     
         3 . The plastic of  claim 1  wherein the plastic is used to form a representative group of packages.  
     
     
         4 . The plastic of  claim 1  wherein the package is constructed of a monolayer of plastic material.  
     
     
         5 . The plastic of  claim 4  wherein about 20 to about 100% of the package comprises from about 0 to about 1900 ppt of 8-Nonenal.  
     
     
         6 . The plastic of  claim 3  wherein the representative group of packages are food-bearing packagse constructed from a mono-layer of plastic material.  
     
     
         7 . The plastic of  claim 3  wherein the level of said 8-Nonenal of a stored food or beverage product stored in the representative group of packages for 7 days at a temperature of 150° F. ranges from about 0 to about 400 ppt.  
     
     
         8 . The plastic of  claim 1  wherein the 8-Nonenal level has been reduced in the plastic to range from about 0 to about 1800 ppt by stripping the 8-Nonenal from the plastic.  
     
     
         9 . The plastic of  claim 1  wherein the 8-Nonenal level is limited to range from about 0 to about 1800 ppt by the addition of anti-oxidants to the plastic.  
     
     
         10 . The plastic of  claim 1  wherein the 8-Nonenal level is limited to range from about 0 to about 1800 ppt by limiting the metals content of colorants added to the plastic ranges from about 1 to about 1000 ppb.  
     
     
         11 . The plastic of  claim 1  wherein the 8-Nonenal level is limited to range from about 0 to about 1800 ppt by the addition of processing aids to the plastic material.  
     
     
         12 . A package formed substantially from plastic, comprising from about 0 to about 1800 ppt of 8-Nonenal for about 20 to about 100% of the package.  
     
     
         13 . The package of  claim 12  wherein the package forms a representative group of packages.  
     
     
         14 . The package of  claim 12  wherein the package is substantially free of perceptible off flavor.  
     
     
         15 . The package of  claim 12  wherein the package is food bearing, beverage bearing or a mixture thereof.  
     
     
         16 . The package of  claim 12  wherein the package comprises a multi-layer construction having an inner layer such that at least one of the layers comprise recycled plastic.  
     
     
         17 . The package of  claim 12  wherein the package is constructed from a monolayer of plastic material.  
     
     
         18 . The package of  claim 13  wherein the level of said 8-Nonenal of a stored perishable item stored in the representative group of packages for at least 7 days at a temperature of ranging from about 100 to about 150° F. ranges from about 0 to about 400 ppt.
