Mars owned Wrigley is bringing the production of Life Savers mints in-house by expanding its  plant in Chattanooga, Tennessee. The relocation is expected to be complete by the end of 2010. This move is a part of a strategy which aims to manufacture most of the core products in-house. This way Wrigley expects to improve business from these brands. Life Savers was being manufactured by a Canadian company for Wrigley. Wrigley is planning to invest USD 28 million to expand its Jersey Pike plant in Chattanooga, Tennessee. It is expected that the expansion building work will finish before the end of 2010 and new equipment will be installed by mid-2011. The plant mainly manufactures 'Life Savers Gummies' and currently employs 265 full-time and temporary employees.
