The Southern Champion Tray 24263 bakery box is made of SBS paperboard, which is white on the inside and outside, has an attached top, and can be used to hold and carry baked goods. White SBS (solid bleached sulfate) paperboard is thicker and more rigid than paper, is suitable for holding baked goods, and can be recycled - just be sure to remove the window film before placing in the bin. The attached top flips open to insert or remove baked goods. When closed, the top fully overlaps the bottom. A cellophane window provides a view of the box's contents. The box has a four-corner beers design with four glued corners for sturdiness. The front of the box can be unlocked and opened for front-loading. Diagonal scores allow the box to be folded flat for storage or transport. The box measures 14 x 10 x 4 inches (L x W x H), which is perfect for a 1/4 sheet cake or other baked goods.
