When you discuss or quote from a product label or packaging information, you do not generally need to create a works-cited-list entry. You can provide all necessary details in your prose:

Food-and-beverage packaging frequently touts a product’s healthy qualities. For example, a package produced in 2013 for Yogi Green Tea Super Antioxidant—a tea sold by the East West Tea Company—notes, “Antioxidants help combat the effects of free radicals, those unstable molecules produced in the body as by-products of aging, pollution and stress.”
