Ethylene interpolymers having improved color

An ethylene interpolymer product comprising:

• greater than 2.5 ppm of a first total catalytic metal and having (i) and/or (ii):
• (i) an improved (decreased) Yellowness index (YI);
• (ii) an improved (increased) Whiteness Index (WI);
• wherein improved is relative to a polyethylene composition having less than 2.5 ppm of a second total catalytic metal;
• wherein Yellowness Index and Whiteness Index are measured according to ASTM E313-10;
• wherein said ethylene interpolymer product comprises:
• (i) from about 15 weight percent to about 60 weight percent of a first ethylene interpolymer having a melt index from about 0.01 dg/minute to about 200 dg/minute and a density from about 0.855 g/cm3 to about 0.975 g/cm3;
• (ii) from about 30 weight percent to about 85 weight percent of a second ethylene interpolymer having a melt index from about 0.3 dg/minute to about 1000 dg/minute and a density from about 0.89 g/cm3 to about 0.975 g/cm3;
• (iii) optionally from about 0 weight percent to about 30 weight percent of a third ethylene interpolymer having a melt index from about 0.5 dg/minute to about 2000 dg/minute and a density from about 0.89 g/cm3 to about 0.975 g/cm3;
• wherein weight percent is the weight of said first, or said second, or said third ethylene polymer divided by the total weight of said ethylene interpolymer product;
• wherein said first ethylene interpolymer is synthesized using a single site catalyst formulation, said second ethylene interpolymer is synthesized using a first heterogeneous catalyst formulation and said optional third ethylene interpolymer is synthesized using a second heterogeneous catalyst formulation.
