Abstract:
The incorporation of organic and FD&C pigments that meet FDA specifications for food packaging materials into resinous articles is accomplished by dispersing the pigments into a non-toxic mineral or vegetable oil formulation which contains glycerol monooleate and zinc stearate, the formulation then being added to the resin and mixed. Resinous articles colored in this manner can be utilized safely as direct food contact packaging, for example, decorative grass, which enables candies to be placed directly on the grass without incurring the expense of overwrapping the candies with a resin film which meets FDA and USDA requirements and which eliminates the hazard involved when candies are inadvertently or unknowingly placed on the decorative grass. The resinous materials which may be colored by the organic and FD&C pigments include polyolefin resins.
