Abstract
A blow-molded, luminescent, polyethylene food or beverage container or bottle which glows-in-the dark due to the presence of zinc sulfide luminescent pigment in the polyethylene resin at a level of from about 0.075 to about 1.2 percent by weight. The blow-molded, luminescent, polyethylene beverage container or bottle is designed to contain an acidic beverage. Even after prolonged storage in the container or bottle, the acidic beverage contains less than 0.25 ppm of zinc.
