When should I use a Snap-Lock (1-2-3) bottom instead of a Reverse Tuck End (RTE) box?

Whenever your product weighs more than 180–250 grams (such as glass candle jars, ceramic mugs, or 100ml+ glass bottles). A standard bottom tuck flap can slip open under concentrated downward weight, whereas the 1-2-3 interlocking bottom distributes the load across all four walls.

What is the difference between a 1-2-3 Snap-Lock Bottom and an Auto-Lock (Crash-Lock) Bottom?

A 1-2-3 Snap-Lock bottom requires no bottom gluing during manufacturing (saving folder-gluer setup costs) and is assembled by hand in three quick folds. An Auto-Lock bottom is pre-glued at the factory for high-speed automated packing lines.

How is the bottom flap depth (H_bottom_lock) calculated for safe weight capacity?

Our engine calculates the primary anchor and male locking tongue depth at 65% of the box width (0.65 * W) with a central interlocking slot at 50% width, ensuring full overlap across the carton center of gravity.

Can I cut a Snap-Lock 1-2-3 bottom carton on a flatbed die-cutter, CO2 laser, or digital cutter?

Yes! The exported 1:1 DXF, SVG, and PDF files separate CUT (Red) and CREASE (Blue) onto dedicated CAD layers compatible with Bobst flatbed die-cutters, Kongsberg/Zünd tables, and CO2 lasers.

Production Engineering Note: Filled 8oz glass candle jars weigh ~420g. Never use a standard bottom tuck flap—this 1-2-3 interlocking snap-lock bottom prevents the jar from falling through the base.

Structural Geometry & Material Reference (ECMA A60.20 / FEFCO 0216 Snap-Lock Bottom)

The ECMA A60.20 / FEFCO 0216 Snap-Lock Bottom (commonly called a 1-2-3 Bottom Folding Carton) is the premier heavy-duty retail box structure engineered for glass candle jars, ceramic coffee mugs, beverage bottles, and heavy cosmetics that would push open a standard tuck-end bottom. Its base consists of four interlocking flaps—a slotted anchor flap, two side hook flaps, and a male locking tongue—that snap together sequentially (1-2-3) to form a high-capacity load-bearing floor without bottom glue.

Total Flat Blank Width (W_blank)

W_blank = W_glue_flap + 2(L) + 2(W) + 3(T)

Sums the side glue flap, two primary panels (L), two side panels (W), and three vertical score line allowances.

1-2-3 Interlocking Bottom Depth (H_bottom_lock)

H_bottom_lock = 0.65 * W

Sets the structural overlap depth of the primary male tongue and female anchor slot so the base supports heavy vertical loads without sagging.

Total Flat Blank Height (H_blank)

H_blank = H_top_tuck + W + H + 0.65(W)

Combines the top friction tuck flap, top lid closure panel (W), main carton height (H), and bottom 1-2-3 snap-lock flaps.
