A white random-angle uniform color packaging product. The packaging wall includes a composition useful for blocking light in the spectral range of about 200 nm to about 1200 nm. The composition has polyester, polymethylpentene and light scattering pigments. The composition optionally includes at least one other colorant. The polymethylpentene and the light scattering pigment each comprise from about 0.1% to about 0.5% by weight of the wall. Polyester and polymethylpentene are immiscible, and when subjected to orientational stress, the composition yields a goniochromatic packaging article. |
