Abstract: Multi-layered packaging materials. In an embodiment, a packaging material includes: an outer layer comprising a colorant and from about 70 wt % to about 99 wt % of a first post consumer resin (PCR); and an inner layer comprising a polymer and being about 3 wt % to about 99 wt % of the total packaging material. The packaging material can also include a middle comprising another colorant and from about 70 wt % to about 100 wt % of another PCR. In another embodiment, a packaging material includes: an outer layer comprising a first colorant and from about 70 wt % to about 99 wt % of a first virgin polymer; a middle layer that is about 40 wt % to about 95 wt % of the total packaging material, the middle layer comprising a PCR; and an inner layer comprising a second virgin polymer. The foregoing packaging materials can be made by co-extruding the different layers therein.
