This month, Rumble all-natural shakes made their U.S. debut in Ball Corp.’s Alumi-Tek bottles. The aluminum bottles are reclosable, which offers on-the-go convenience for consumers. “By putting their shakes in the Alumi-Tek bottle, Rumble differentiates itself as a premium brand that consumers can’t miss,” said Bruce Doelling, vice president of sales for Ball’s North American metal beverage packaging business, in a statement. "In addition to having the same advantages as aluminum cans, such as infinite recyclability and the ability to cool down quickly, our proprietary Alumi-Tek bottles provide reclosability for consumers on the move."
