Our Customers

A kraft mailer is one of the only pieces of packaging a customer physically holds before they see your product, which makes it genuinely valuable, low-cost brand space if you print on it, and a missed opportunity if you leave it plain. This guide covers what actually prints well on kraft paper, what a custom run costs in time and minimum order quantity, and how to get from a design idea to a finished, branded mailer without wasting a production run on a mistake.

Why the mailer is worth printing at all

A plain box or carton is often opened and discarded before the customer engages with it emotionally. A mailer is different, it is opened in the customer’s hands, at the moment of highest attention in the whole delivery experience. A printed mailer turns that moment into a repeatable, recognisable brand touchpoint: the same colours, the same mark, the same feel, every time a customer receives an order. That repetition, not a single striking one-off design, is what actually builds recognition over a series of purchases.

What prints well on kraft, and what does not

  • Bold, high-contrast marks print reliably. A simple logo, a single strong colour, clean typography, these read clearly against the natural brown of kraft paper.
  • Fine detail and pale colours struggle. Thin linework, subtle gradients, and light colours like pastels or pale yellow tend to lose definition or contrast against kraft’s natural tone, particularly on uncoated stock.
  • White ink and spot colour both work, differently. A white or light spot colour printed directly onto kraft can look striking precisely because of the contrast, while full-colour process printing on kraft reads warmer and more muted than the same file would on white stock. Decide which effect you actually want before finalising artwork.
  • White kraft is an option if your design genuinely needs to print the way it would on a white background, at a different cost and slightly different feel to natural brown kraft.

Designing for the mailer, not just the logo

A logo that looks right on a business card or a website does not automatically translate to a mailer. Consider the mailer’s actual proportions, most kraft mailers are taller than wide or vice versa depending on size, and design around that shape rather than shrinking a square logo into it. Consider where the flap and seal sit, artwork placed across that line can end up partially hidden once the mailer is sealed, and consider whether the design should repeat as a pattern across the surface or sit as a single centred mark, both are common, valid choices with a different production cost.

Print methods and what they mean for your order

MethodBest forConsideration
Flexographic printLarger production runsLower cost per unit at volume, higher setup cost, less economical for small runs
Digital printSmaller or variable runsLower setup cost, higher cost per unit, practical for testing a design before a bigger commitment
Single spot colourSimple logos and wordmarksCheapest print option, most reliable result on kraft
Full colour processDetailed, multi-colour artworkHigher cost, test carefully for colour accuracy on the actual kraft stock

Minimum order quantities, and why they exist

Custom printing carries a setup cost, plates, print-run configuration, colour matching, that is largely fixed regardless of how many mailers come off the run. That is why a minimum order quantity exists and why it is usually higher for printed mailers than for a plain stock size. Some suppliers deliberately keep minimums low specifically to make branded packaging accessible to smaller businesses rather than only large-volume buyers, it is worth asking directly what the minimum actually is and whether it scales down for a first, smaller test run before assuming you need to commit to a large volume from day one.

The proof and sample stage: do not skip it

  1. Digital proof. Review a mockup of the artwork on the mailer’s actual dimensions, checking placement against the seal and flap.
  2. Physical sample. A screen proof and a printed sample often look different on kraft, colours read differently on paper than on a monitor. Always get a physical sample before committing to full production.
  3. Check under real light, not just under office lighting, kraft’s natural tone can shift how colours appear depending on the light source.
  4. Approve in writing before the full run starts, this protects both you and the supplier if something does not match expectations later.

Lower-cost branding if you are not ready for a full print run

If your order volume does not yet justify a custom-printed mailer, a plain kraft mailer paired with a printed sticker, a branded insert card, or custom-printed water activated sealing tape delivers a branded unboxing at a much lower minimum order quantity. This is a genuine, common starting point, not a lesser option, and it is easy to upgrade to full mailer printing later once volume supports it.

Branding across your whole mailer range

If you use more than one mailer format, flat for documents, padded for fragile items, gusseted for bulkier orders, keep the branding consistent across all of them rather than only printing your highest-volume format. A customer who receives an unbranded mailer for one order type and a branded one for another notices the inconsistency, even if they cannot immediately articulate why the experience felt slightly off.

Common artwork mistakes that cost a reprint

  • Designing on a white background file and assuming it will translate directly to kraft, always mock the design up on the actual paper colour, not a white canvas, before finalising.
  • Ignoring the seal line. A design that looks complete in the file can end up split awkwardly once the mailer is folded and sealed if the artist did not account for where that fold falls.
  • Using a colour reference from a screen rather than a physical swatch. Screens display colour inconsistently between devices, and none of them show how a colour will actually sit on kraft paper’s textured, absorbent surface.
  • Approving from a digital mockup alone. A rendered mockup image is a guide, not a guarantee, the physical sample step exists specifically to catch what a mockup cannot show.

Each of these is a genuinely common, avoidable reason a first print run needs to be redone, and each is caught by the proof-and-sample process described above if it is actually followed rather than skipped to save time.

How much lead time to plan for

A custom print run takes longer than a stock reorder: time for artwork approval, a proof cycle, and the production run itself, before delivery. Build this into your planning ahead of a launch, a seasonal campaign, or a rebrand, rather than treating a printed mailer order the same way you would treat restocking plain kraft mailers you already use every week. Ordering with real lead time also gives you room to catch and fix an issue at the proof stage without it becoming a rushed, costly problem right before you need the stock.

Frequently asked questions

Can any kraft mailer be custom printed?
Yes, flat, padded, gusseted and kraft-bubble mailers can all be printed, the print process is largely independent of which mailer format you have chosen.

What colours print best on kraft paper?
Bold, high-contrast colours and simple marks print most reliably. Fine detail and pale colours tend to lose definition against kraft’s natural brown tone, particularly on uncoated stock.

What is the minimum order for custom-printed kraft mailers?
It varies by supplier and print method, and should be quoted against your actual volume rather than assumed. Ask specifically whether a smaller first test run is available.

Should I get a physical sample before a full print run?
Always. A screen proof and a printed sample on kraft can look noticeably different, and approving the physical sample in writing protects both you and the supplier.
