1-2-3 Bottom Boxes | Tuck Boxes

How the 1-2-3 Base Sequence Works

The 1‑2‑3 bottom name comes from the order in which the base flaps fold and lock together — each flap reinforces the next until the base is firmly closed.Once you learn the sequence, the motion becomes very fast and repeatable, giving you a strong base without glue, tape, or machinery.

Comparing 1-2-3 Bottom to Other Heavy-Duty Bases

Snap lock, auto‑lock, and 1‑2‑3 bottoms all increase weight capacity compared to simple tuck bottoms, but they do so in slightly different ways.1‑2‑3 bottoms are a good fit when you want a very strong, flat interior base surface and do not mind a short learning curve for assembly.

• 1‑2‑3: very strong, flat base; manual folding sequence
• Snap lock: fast manual assembly; excellent for many jarred goods
• Auto‑lock: fastest assembly; higher manufacturing cost but ideal for large runs

Typical Products That Use 1-2-3 Bottoms

You will often see 1‑2‑3 bottoms on heavier grocery items, glass jars, multi‑item kits, and boxed gifts that must feel solid in the hand and reliable on the shelf.The structure is also popular for specialty and gourmet products where both perceived sturdiness and presentation quality are part of the value proposition.
