Half slotted containers are similar to regular slotted containers, but only have one set of flaps. The outer flaps on the bottom of the Half Slotted Container meet in the centre and can be taped, glued, or stapled together to close the container; the top is open. This design is frequently used as a base and lid combination. Because the opposite side of the box is open, it can slide over an item. Ideal for large and heavy items like refrigerators and washing machines.
