摘要: A sheet of material and package made using the sheet of material. The sheet of material having an having an outer diffuse layer and an inner light piping layer adjacent the diffuse layer. The sheet transmits light to the outer surface of the outer diffuse layer. The outer diffuse layer has a specular area formed thereon through which light from the light piping layer can exit in a substantially non-diffuse manner from the outer surface of the outer diffuse layer.
