Patent ID: 8859091

Claim:
A polymeric sheet comprising: a first polymeric layer; wherein the first polymeric layer comprises a first additive composition that allows for a light transmission of greater than or equal to about 75%; the first additive composition comprising an additive; the additive being a light scattering additive, an optical brightener, or a combination comprising at least one of the foregoing additives; and a second foamed layer; the first polymeric layer being in operative communication with the second foamed layer; the polymeric sheet having a percent light transmission as measured according to ASTM D 1003 of about 3% to about 80% at a thickness of greater than or equal to about 1,000 micrometers, wherein the light transmission of the polymeric sheet is uniform across the polymeric sheet, the polymeric sheet having a variation in luminance transmission as measured in a 13 point uniformity test that is less than or equal to about 5% across the polymeric sheet and the polymeric sheet having a surface area of greater than or equal to about 10000 square centimeters.
