Overview

What is a folding carton?

They're built for the shelf, not the mail. A carton is too thin to go through a delivery truck on its own, so if you sell online it goes inside a mailer or shipping box.

A folding carton is a box made from a single sheet of paperboard, cut and creased so it folds into shape. It arrives flat and glued along one side, and your packers pop it open, fill it and close the ends.

The closures are what change. A tuck end tucks a flap in at the top and bottom. A lock bottom snaps shut underneath, for heavier products. Both print edge to edge on every panel.

  • Panels. Front, back and sides, all printable. The back usually carries ingredients and barcodes.
  • Tuck flaps. Close the top, and the bottom on a reverse tuck end.
  • Glue flap. One side seam, glued before delivery so the carton opens in one move.
  • Lock bottom (optional). Interlocking base flaps for heavier products like jars.

Carton or mailer box?

The question is simple: does the box go in the mail on its own?

If you sell in stores and online, use both: the carton for the shelf, and a custom mailer box or shipping box around it for the mail.

Sizing

Measure from the opening

Carton sizes are written length x width x depth, and they refer to the opening, not how the box sits on a table. Get that wrong and everything else can be right while the box is still wrong.

Take a candle 3 inches square and 5 inches tall, in a carton that opens at the top. The opening is 3 x 3, so the carton is 3 x 3 x 5. Order it as 5 x 3 x 3 and the tuck ends up on the long side, and it won't stand on a shelf.

Send your product's size and which end it goes in through. We add clearance on the dieline. How to measure a box has the full method.

Products that go in folding cartons

Finishes

Cartons take finishes best.

Smooth paperboard is where finishes look sharpest. Still, most cartons need one, not four. Aqueous coating goes on every box by default.

Foil stamping

Crisp on white board. Best on a logo or product name.

Embossing

A raised mark you can feel. Sharpest on smooth board.

Spot UV

Gloss on one area of a matte carton. Not for small text.

Aqueous coating

Default on every carton.

How it works

Four steps, one person.

The specialist who picks up your first email stays with the project until the boxes arrive.

  1. Step 01

    Tell us what you're packing

    Send the product dimensions, how it ships and how many you need. A photo on a ruler is enough to start.

  2. Step 02

    We draw the structure

    Your packaging specialist builds the dieline around your product. Structural design is free.

  3. Step 03

    You approve the proof

    Drop your artwork onto the dieline. We check bleed, folds and barcodes, and send a digital proof.

  4. Step 04

    We make and ship

    Production takes 10–12 days on most orders. Boxes ship flat, packed in cartons, to your door.

FAQ

Custom folding cartons: questions.

What is the minimum order for custom folding cartons?

50 units per design. Enough to put a carton on a real shelf before you order a bigger run.

What's the difference between straight tuck and reverse tuck?

On a straight tuck end, the top and bottom flaps tuck in from the same side. On a reverse tuck end, they tuck from opposite sides. Reverse tuck is the more common, lower-cost choice.

Can a folding carton be shipped on its own?

No. Paperboard is too thin for the mail. Put the carton inside a mailer or shipping box.

Do folding cartons arrive flat?

Yes. They arrive flat with the side seam already glued, so they open in one move.

How long do custom folding cartons take?

10–12 days on most orders, counted from proof approval. Shipping time is on top.

Honest fit

When not to hire us.

The box goes in the mail by itself

A paperboard carton gets crushed in a delivery truck. Use a corrugated mailer instead.

You need fewer than 50 boxes

Our minimum is 50 units. For 10 or 20, a stock box with a printed sticker will cost you less.

You need boxes next week

Production runs 10–12 days before shipping. If your launch is sooner, buy stock boxes now and switch to custom for the next run.

You want plain brown boxes

If nothing gets printed, a stock box supplier is cheaper and faster. We're worth it once the box carries your brand.

What size is your product?

Send the length, width and height, and which end it goes in through. We'll draw the carton and send a proof.
