A one-piece box is cut and folded from a single sheet with a self-locking bottom, so it arrives flat and folds into a finished box in seconds with no glue and no assembly line. It is the practical workhorse for shipping and retail: subscription boxes, apparel, food to go, hardware, and mailers. We make custom one-piece boxes with no minimum order, so you can run 100 to test and reorder at a lower per-box price as volume grows, at a price we will quote against any competitor.

The most common one-piece styles are the 1-2-3 bottom (snap-lock), the four-corner tray with a separate or attached lid, and the roll-end tuck front used for mailers. We build them in 14pt to 24pt SBS or kraft for retail, or E and B-flute corrugated when the box has to ship and take a knock. Finish with your print, matte or gloss lamination, and a die-cut window if you want the product seen.

Send the product size and weight and how it will ship, and we will spec the board and the lock, then build a dieline and a free proof, with free samples and free shipping. Standard turnaround is about 10 to 14 business days after proof approval, with rush handled case by case.

One-piece box FAQ

What is a one-piece box?

A one-piece box is made from a single scored sheet with a self-locking bottom or tray, so it folds into shape without glue. Common styles are the 1-2-3 snap-lock bottom, the four-corner tray, and the roll-end tuck mailer.

Does a one-piece box need glue or assembly?

No. The single sheet locks into shape by hand in seconds, which saves time and cost on filling.

Can a one-piece box ship products safely?

Yes. For shipping we build it in E or B-flute corrugated so it holds up in transit; for retail we use SBS or kraft.

Is there a minimum order for one-piece boxes?

No. We make custom one-piece boxes with no minimum order, so you can start at 100 and reorder at a better per-unit price at volume.
