Our line of Naturally Kraft Lock Corner Bakery Boxes maintains a classic style, while effectively respecting our environment. Kraft Bakery Boxes are the industry’s standard, economic choice, using 20% less fiber than other box materials. Each one-piece box has an attached tuck-in lid and can be used to hold and carry a variety baked goods. The lock corners facilitate assembly and enable the box to be folded flat for storage or transport.
