The emissivity value for acrylic ranges from about 0.90 to 0.95. For thin material, less than 1/8" down to film thickness, the emissivity can be below 0.90. Emissivity depends on absorption in the IR range, and for thin materials, such as films, the absorption is less in the IR range, due to thickness.
