Award-winning DiamondClear® ConAgra Foods’ Hunts® Ketchup was among the first to adopt Constar’s DiamondClear technology. In 2007, the innovative package captured two Ameristar Awards, the prestigious 3‑M Sustainability Award and the Food Category Award, and was one of only five North American products to win an international WorldStar Award.  The Ameristar Awards are to the packaging industry what the Oscars are to the film industry. Constar is fortunate to have won numerous Ameristar Awards on behalf of its customers over the years. |
