Four Corner Cake Box
A four corner cake box has creased corners that fold inward to raise four walls around a flat base, creating an open-top tray specifically sized for cakes, pies, and pastry items. The corners lock into position without glue or tape through interlocking tab cuts in the material. The open top allows bakeries to place a dome lid, clear PET cover, or flat board lid over the cake after decorating. Standard sizes run from 6x6 inches for single-layer cakes up to 16x16 inches for large sheet cakes, with wall heights of 3 to 5 inches. Construction uses food-grade white cardboard or SBS with grease-resistant coatings rated for direct food contact. The flat-packed design ships in stacks of 50-100, and assembly takes about 3 seconds per box. The four-corner fold creates a sturdy base that distributes weight evenly under heavy frosted cakes. Cubit produces custom four corner cake boxes from 100 units.
