Overview & Specifications
What Is a Straight Tuck End Box?
A straight tuck end box, or STE carton, is a paperboard folding carton with a glued side seam and a tuck flap at each end, where both the top and bottom tucks hinge from the same main panel. Because both ends close the same way, the front and back panels stay consistent, which makes artwork, windows and hang tabs simpler to plan.
How the Same-Side Tucks Work
The format works through three features on one blank.
01
Glued Side Seam
The carton is glued into a flat tube during production and opens into a rectangle when squared up.
02
Same-Panel Tuck Flaps
Both tuck flaps hinge from the same main panel. Each folds over its end and slides inside the facing panel, so both ends open in the same direction.
03
Dust Flaps
Side-panel flaps fold under each tuck to close the corners and support the closure.
Anatomy of a Straight Tuck End Box
01
Front Panel
Main display face, uninterrupted by tuck hinges.
02
Back Panel
Carries both tuck flaps.
03
Top and Bottom Tucks
Hinge from the same panel.
04
Dust Flaps
Fold in under each tuck.
05
Glue Flap
Forms the side seam.
With both tucks on the same panel, the top and bottom flaps print in the same orientation, so end-panel text reads consistently when the carton is turned.

Application guide
When Is a Straight Tuck End Box the Right Choice?
A straight tuck end box suits retail products where the front panel is the selling face, such as cosmetics, skincare, soap, small accessories and peg-hook items. It is also the structure behind Packaging Dock's hang tab tuck boxes.
01
Consistent
Consistent Front Presentation
Both ends open toward the same side, so the front panel carries uninterrupted artwork, a window or a product photo.02
Platform
Platform for Display Features
Hang tabs, windows and inserts can be added to the same straight tuck structure.03
Re-Openable
Re-Openable Ends
Both tucks open and re-seat for product access, unless a seal or tear strip is added.04
Alternative
When Another Format May Fit Better
When a consistent front is not needed, a Reverse Tuck Box closes its ends in opposite directions and can fit efficiently within the blank on many proportions. For a locked bottom, see the Auto Lock Box or Snap Lock Box, and for peel-and-seal ends, the Seal End Box.

What Size Straight Tuck End Box Do You Need?
Quote the carton by inside length × width × depth, where length and width form the opening at the tuck end and depth is the distance between the ends. For a hang tab carton, the tab is added above the top end on the dieline and does not change the inside size.
How Product Size Becomes Carton Size
The figures below are planning references, not fixed manufacturing rules; final allowances depend on product shape, insert and board.
| Step | Typical Allowance |
|---|---|
| Product to inside length and width | Add about 1–2 mm (1/16 in) so the product slides in |
| Product to inside depth | Add about 2–3 mm so both tucks seat cleanly |
| With an insert | Size to the insert's outer dimensions |
| Inside to outside | Each dimension grows by about two board thicknesses |
Paperboard Caliper Reference
| Board | Typical Thickness | Typically Suited To |
|---|---|---|
| About 14–16 pt | About 0.36–0.41 mm | Small, light retail items |
| About 18–20 pt | About 0.46–0.51 mm | Cosmetics, soap, hang tab cartons |
| About 22–24 pt | About 0.56–0.61 mm | Larger cartons and heavier contents |
| About 26–28 pt | About 0.66–0.71 mm | Large front-led display cartons |
| E- or F-flute corrugated | About 0.8–1.6 mm | Extra edge strength |
| B-flute corrugated | About 3 mm | Large or multi-unit cartons |
Important: Use these as reference values only. A hang tab carries the carton's full weight on the hook, so board for hanging products is checked against the packed weight on a sample.
If you are unsure, share the product dimensions and weight with the quote request, and the carton is sized around them.
Which Way Should the Front Face?
Choose the panel that will face the shopper before the dieline is drawn: the tucks hinge from the back, so the front stays clear. On shelf, the carton reads as one continuous front face.
