New Kinds of Bottles

Packaging companies are also interested in developing bottles that are as hard as glass but will not shatter if mishandled. The plastic bottles contain clay nanoparticles that are as hard as glass but far stronger, so the bottles are less likely to shatter. The layout of the nanoparticles is keeping the liquid from spoilage and flavor problems and giving it up to a six-month shelf life. By embedding nanocrystals in plastic, researchers have created a molecular barrier that helps prevent the escape of oxygen. Nanocor and Southern Clay Products are nowworking on plastic beverage bottles that may increase shelf life to 18 months.
