Tuck-End Boxes: Reverse, Straight, and Auto-Lock

Tuck-end boxes are the everyday folding cartons behind most retail packaging - from cosmetics to supplements. They ship flat, assemble by tucking flaps, and print in full color. Here are the three main tuck-end styles and how to pick the right one.

What is a tuck-end box?

A tuck-end box is a folding carton whose top and bottom close with tuck flaps rather than glue. It is lightweight, affordable, and ships flat - ideal for lightweight retail products.

The three tuck-end styles

• Reverse tuck end (RTE) - flaps tuck from opposite directions; economical and common.
• Straight tuck end (STE) - flaps tuck from the same direction so the front face stays clean; great for premium looks.
• Auto-lock (1-2-3) bottom - a pre-glued base that snaps into place for heavier items and fast assembly.

When to use each

Choose RTE for low cost, STE for a cleaner front panel, and auto-lock bottoms for heavier products or high-speed packing. All are types of folding cartons.

Design tips

Keep your logo on the main face (use STE if the front must stay seamless), and start from a dieline so artwork aligns with folds. Explore printing and finishing in our complete guide to custom printed boxes.
