Tuck end is a family of folding carton styles, not a single box. They all share the same idea: the carton ships flat, you pop it open, and the ends close by tucking a flap into the body. Which variant you pick changes the front panel appearance, the board consumption and how fast the box can be packed.
The variants side by side
| Style | How it closes | Pick it when |
|---|---|---|
| Straight tuck end (STE) | Top and bottom flaps both tuck in from the back panel | The front face must be uninterrupted, because both tuck slits sit at the rear |
| Reverse tuck end (RTE) | Top flap tucks from the back, bottom flap tucks from the front | Cost matters more than a perfectly clean front, since the layout nests more efficiently on the sheet |
| Auto bottom (crash lock) | Glued base that locks flat as the box is opened, top tucks | Hand packing at speed, or heavier contents that would push a tucked base open |
| Seal end | Both ends glued closed on a filling line | High volume automated filling rather than hand packing |
The details that decide whether it works
- Dust flaps. The small side flaps stop contents escaping and give the tuck something to bear against. Skimping on them is why cheap cartons feel flimsy.
- Tuck slits and locks. A slit lock keeps the tuck closed after the first opening. Without it, a box that gets opened and closed repeatedly starts to gape.
- Board caliper. Too thin and the tuck creases on the way in. Too thick and it fights the slit and buckles the panel. This is worth confirming against your actual product weight.
- Grain direction. Scores that run with the grain fold cleanly. Against the grain they crack, which shows badly on a dark printed panel.
Matching the style to the product
Light retail goods such as cosmetics, supplements, small electronics accessories and confectionery sit comfortably in a reverse tuck end. Anything where the front panel is doing the selling, and you do not want a visible tuck line breaking the artwork, argues for a straight tuck end. Anything with real weight, or anything a team is packing by hand hundreds of times a shift, argues for auto bottom, because the base does not need to be assembled. See auto bottom boxes for how that base is built.
Ordering, price and turnaround
The minimum order is 100 boxes. Pricing starts from about $0.48 per unit at bulk volumes and is confirmed on your written quote, since caliper, size, print and finish all move it. The die and the plates are included, which matters on tuck end work because a change of style means a change of die, and you are not paying for that tooling twice.
Three lanes are quoted per product: rush (expedited production plus air freight, with a premium of about 7 to 25% depending on the job), standard (air) and cost saver (sea). Production starts from about 7 business days, plus 2 to 5 for delivery, and specialty imported items can run up to about 12 weeks. iBox Factory produces in West Chicago and in Guangzhou, and design support and a digital proof come with every order.
