1-2-3 Bottom Boxes are cited as snap lock boxes having three flaps or fold at the bottom. The box takes it constructed shape as the three flaps are interlocked together. The side flaps are a perfect frame and are designed in such a way that once they are interlocked they give a strong closure at the bottom ensuring the safety of the product enclosed. Just like a jigsaw puzzle, the tray of snap lock boxes are joined and assembled in a complete shape that provides long lasting permanence. Indifferent to a tuck bottom box they are made to hold weight of the products more efficiently. Definitely, a three flapped bottom provides more strength than tuck bottom boxes. Snap boxes are more economical than tuck bottom boxes or auto-lock boxes. The bottom flaps, when interlocked, are capable of providing more strength to the extended top flap and allows it to tuck in firmly in its place.
