Custom Printed Mailer Boxes With Your Artwork, Cut to Size

What makes a mailer box custom printed?

The artwork goes straight onto the corrugated sheet before it is cut and creased. There is no label or sleeve to apply, so every box comes off the bundle already dressed.

You choose where the ink goes: the outer walls and lid, the inside faces, or both. You also choose how much ink, from one flat colour on bare kraft to a full colour image that covers every panel. It sits in our printed mailer boxes and finishes range with matt black, white and plain kraft options.

Who orders printed mailer boxes?

Small brands that post from a unit or a spare room tend to reach this point once orders are steady. A plain box works, but a printed one saves time on stickers and stamps.

• Clothing labels sending folded tops with a printed message under the lid.
• Beauty and skincare sellers who want the box colour to match the product range.
• Subscription businesses changing the inside print each quarter while the outside stays the same.
• Craft and gift shops putting a pattern on every face for a wrapped look.
• Bakers and sweet shops posting tins or trays with their logo on the lid.

How many colours should the print use?

The number of colours shapes both the look and the quote. One colour suits logos and short lines of text. Two colours add an accent, such as a coloured logo with black contact details. Full colour handles photographs, gradients and dense patterns.

If you are unsure, send the artwork and we will suggest the simplest print that keeps it looking right.

Kraft or white-lined board for printing?

Brown kraft gives ink a warm, slightly muted tone. Dark colours read well on it, but pale ones fade into the brown unless a white underprint goes down first.

White-lined board shows colour as it looks on screen, near enough, and keeps pastels clean. Both come in E-flute 1.5 mm or B-flute 3 mm. Our page on choosing E-flute or B-flute board sets out when the thicker sheet pays its way.

Printing the inside of the lid

The underside of the lid is the first panel anyone sees once the box opens. A thank-you line, a pattern, a social handle or care instructions all fit there.

Inside print runs on the same sheet as the outside, so the two designs need to line up with the folds. We mark every crease and panel on the proof so you can see which way up each one sits. A short read on printing inside the lid of a mailer box covers safe areas and bleed.

What size printed mailer box do I need?

Size the box to the packed item, not to the artwork. Add 3 to 5 mm a side for clearance, then fit the design to the panels that result.

Our typical starting size is 250 x 180 x 80 mm inside, which takes a folded jumper or a small gift set. If you post as a Royal Mail Large Letter, the outside must stay within 353 x 250 x 25 mm; a Small Parcel allows 450 x 350 x 160 mm. Check the current band limits before you order, as both are measured on the outside.

Board thickness counts too. E-flute adds only a few millimetres to each outside figure, while B-flute adds a little more, which can tip a tight box into the next band. Tell us the band you are aiming for and we will size the inside to keep the outside under it.

How does the artwork proof work?

Every printed job gets a free design proof drawn onto the flat box layout. Nothing is printed until you approve it in writing.

1. Send your logo or artwork, ideally as a vector file or a high-resolution image.
2. We place it on a flat dieline showing every panel, fold and flap.
3. You check spelling, colour notes and which panels face up when the box is closed.
4. Ask for changes as often as you need until the layout is right.
5. Approve the proof, and the job moves to the press.

Do printed mailer boxes need inserts?

Soft goods such as clothing rarely need more than tissue. Bottles, jars and sets do better with a die-cut board insert that holds each piece in place, and the insert can carry print too.

Dividers split one box into bays, and paper void fill closes up spare space for odd-shaped items. All three are quoted with the box, so the price arrives as one figure. Tell us what goes in each bay and how the customer should find it, and we draw the insert onto the same proof as the box print.

Mistakes to avoid with custom print

• Sending a low-resolution logo copied from a website and expecting crisp edges.
• Running fine white text on kraft with no white underprint behind it.
• Putting key wording across a fold, where it bends out of sight.
• Designing to the outside size when the size you gave us was the inside.
• Leaving no clear space for the postage label, so it covers the artwork.
• Checking the proof only on a phone without zooming in on small text.
