Wm. Wrigley Jr. Co. has rolled out new, slim-line, 15-stick packaging for the brands that constitute 30% of its U.S. gum business.

The Slim Pack for Doublemint, Spearmint, Juicy Fruit, Big Red, Winterfresh and Extra brands, unveiled at the recent All Candy Expo, coincide with formulation improvements. The Slim Pack is similar in dimensions to the “5” gum pack the company introduced last year.
