The next Whopper you order may look a little different when you take it out of the bag. In fact, the bag may look different, too. Fans don't need to worry: Burger King's packaging is changing, but the Whopper itself is staying the same. Thanks to a partnership with the brand Loop, Burger King will soon test reusable boxes, bags, coffee and soda cups, and more packaging—and it may end up saving customers money. Loop is a "circular packaging service" specializing in zero-waste wrappers and storage containers. All of its products may be cleaned, sanitized, and reused. Starting next year, Burger King will test the new packaging: Customers who opt-in to receive the Loop wrapping pay a deposit, which is refunded upon return. Once the packaging is back in the hands of Burger King, it will be cleaned before its next use. (Related: How did Burger King sales do this year?
