ROSEMONT, Ill. — Retailers, manufacturers, wholesalers and others gathered in Chicago Nov. 11-13 for the Private Label Manufacturers Association's 2007 trade show. At the event, two major private-label studies were presented. One, by Wisner Marketing, discussed ways to leverage private label to rebuild Center Store. Shelf-stable juices were cited as a private-label power category, ranking only behind bottled water and carbonated beverages. Healthier juice options such as reduced-sugar, light and reduced-sodium can help drive new volume, said the study.
