Color core or dual color texture HDPE sheet is a type of high-density polyethylene sheet that has two or more layers of different colors embedded into the sheet, rather than laminated. The top layer is usually a thin cap of one color, while the bottom layer is a thicker core of same color or another color. Which is looking nicer than the original HDPE sheet. The sheet can also have a textured or glossy surface that adds visual appeal and functionality.
