Abstract
White goniochromatic packaging material. The package wall containing a composition useful for blocking light in the spectrum ranges from about 200 nm to about 1200 nm. The composition has polyester, polymethylpentene, and a light scattering pigment. The composition optionally includes at least one other colorant. Each of the polymethylpentene and the light scattering pigment comprise about 0.1 to about 0.5 weight percent of the wall. The polyester and polymethylpentene are immiscible and when subjected to orientation stresses the composition produces a goniochromatic packaging article.
