<P> Union Packaging, a minority - owned, Philadelphia - based paper products company, has supplied much of the packaging for Burger King's North American operations since winning its first contract in 2000 . The original $15 million contract was for paperboard "clamshell" containers and covered 1,250 BK locations in the United States . Union was instrumental in the development of the FryPod carton, and its efforts earned the company a supplier of the year award from Burger King in 2007 . </P> <P> Over time, the company reformulates various products in an attempt to boost sales of the product or to improve the taste, appearance, or physical consistency of the product . One such example of this is the BK Big Fish, the company's fish sandwich offering in North America . Burger King's original fish sandwich, introduced as early as the late 1960s in some markets, was called the Whaler; it was a smaller fish sandwich made with tartar sauce and lettuce served on the small sesame seed roll BK used for their hamburgers . When Burger King introduced its broiled chicken sandwich in 1990, the BK Broiler, it changed the fish sandwich's breading to a panko style, began serving it on an oatmeal - dusted roll that was used for the broiled chicken sandwich, and renamed the product the Ocean Catch sandwich . When BK reformulated the BK Broiler, the company also reformulated the Ocean Catch as the BK Big Fish in its current configuration . The sandwich was again briefly reformulated after the phase - out of the Baguette sandwiches, and was reintroduced as the Big Fish in 2005 . </P> <P> One of the company's larger product reformulations came in March 2011 . The company updated the recipe of its 25 + year - old Chicken Tender product line by reformulating the breading and spice mixture while updating the shape . The new formulation was described by the company as being "more broadly appealing" to the palate of its customers according to statement released by the company . Nation's Restaurant News analyst John Barone stated that the change may also be due to an industry wide move to chicken - based product as a result of raising commodity prices, forcing restaurants to turn towards chicken - based offerings due to the elevated pork and beef prices occurring during the previous year . He added that chicken breast costs have been down or flat during the same period, making it a more appealing choice to companies . The new product push was accompanied with a product tie - in with the movie Hop aimed at the youth market, an adult - oriented advertising campaign pushing convenience and product customization and a nationwide coupon mailing in the United States . Online advertising was emphasized with the release a Facebook gaming application it called the "Tender 8". </P> <P> To generate additional sales, BK will occasionally introduce limited time offers (LTO) that are versions of its core products or new products intended for either long - or short - term sales . Many of these LTO products focus on core menu products such as the Whopper, which has featured variations such as the Texas Double Whopper with added jalapeños, bacon, and pepperjack cheese . Other LTOs include all - new sandwiches like the Chick'n Crisp sandwich (now a permanent item in many regions) and test products such as the company's Great American Burger, which was an attempt at a premium sandwich in 2003 . It was made with a Whopper patty and several new ingredients, including a bakery - style bun; peppered bacon; whole - leaf, as opposed to shredded, lettuce; seasoned mustard; and a special sauce . The burger was served with American cheese, mayonnaise, tomato, and onions . A similar burger was tested in Wisconsin in 1999 . That Great American burger featured a single 8 oz (230 g) burger patty and different toppings . It was designed to be cooked on a forerunner of the current batch broiler . </P>
