<P> In January 2010, BK began to publish a list of which of their products that contain gluten and added menu options designed to help those afflicted with Celiac disease as part of its "Positive Steps" nutrition program . A company representative stated that it understands that its guests have individual dietary needs, and as part of its "Have It Your Way" promise, Burger King offers menu items for individuals with gluten sensitivity . BK food is prepared with several known food allergens, including wheat, milk, soy, and eggs . </P> <P> The range of products sold usually depends on the time of day . Lunch items such as hamburgers and fries are traditionally not served during breakfast time . However, some BK stores do sell food under their "Burgers for Breakfast" program . While for several years the company dictated hours to its franchisees in the United States, that changed with the sale of the company in 2010 . The new owners relaxed the mandated hours for stores to be open from 6 am to midnight Monday through Saturday and 7 am to midnight on Sundays; franchises were encouraged to stay open later or for 24 hours in markets that could support the business . </P> <P> Burger King's product packaging has undergone many changes over the years . Unlike McDonald's, the company never used the clamshell style box made of Styrofoam, so when the environmental concerns over Styrofoam came to a head in the late 1980s, the company touted its use of paperboard boxes for its sandwiches . When McDonald's moved to eliminate its styrofoam packaging, Burger King ran several sarcastically - worded ads in national newspapers stating that it had always wrapped its sandwiches in waxed paper; they welcomed McDonald's "to the club". To cut back on the amount of paper that the company used, the paperboard box was mostly eliminated in 1991; it was replaced with waxed paper . Paperboard boxes are still used for its "finger food" products like Chicken Tenders and Fries, French toast sticks, and desserts . </P> <P> In 2004, the company committed itself to a redesign of its entire packaging line that tied the packaging into its irreverent advertising campaign created by Crispin, Porter + Bogusky . Each product's packaging included a tongue - in - cheek commentary about the product itself . Alex Bogusky, partner and executive creative director of CP + B, stated that BK decided "to create a dialogue with the consumer" by utilizing the large areas of white space found on its packaging at the time . All of its sandwich wrappers, cartons, tray liners, bags, breakfast platters, chili cups, condiments, and regional product packaging received what was described as "quirky ad copy" specifically targeting the 18--34 - year - old male demographic segment . Besides the humorous commentary, the company also created sniglet - type names for things that would appear in its products, such as a "ringer"--a single onion ring that had been accidentally included in an order of fries . </P>
