Medline Industries Inc., the largest privately held U.S. manufacturer and distributor of healthcare products, plans to build a new distribution center in Auburndale that will create about 100 new jobs. The 830,000-square-foot warehouse is the largest new business to come to Auburndale since the Coca-Cola North America packaging plant on Main Street, which opened in June 2003, Amy Palmer, the city’s community development director, said Monday after the company released its announcement.
