Why online brands ship in kraft mailer boxes

A kraft mailer box is a one-piece corrugated box with a hinged lid, dust flaps and front locking tabs that fold together without tape. The fluted core cushions products against knocks in the parcel network, while the unbleached brown liner gives an honest, earthy finish. Because the same box works as both shipper and presentation box, custom kraft mailing boxes suit direct-to-consumer brands that want one package to survive transit and still look intentional when the customer opens it.

E-flute is the usual choice for apparel, cosmetics and small accessories because it stays thin, folds crisply and takes print well. B-flute adds crush strength for heavier items such as candles, jars or books. Kraft liners carry one- or two-color ink cleanly, and dark inks look especially sharp on the brown surface. If you need brighter color, ask about a white inner liner so the inside print pops while the outside keeps its custom kraft shipping box character.

Design for the brown base rather than against it. Black, white and deep colors read well on kraft, while pale pastels tend to fade into the board. Many brands keep the outside minimal, with a logo and return address, then print a pattern or thank-you message inside the lid. Add a printed insert or tissue for a fuller reveal.

Options for custom kraft mailer boxes

Mailer styles

Choose a roll-end front tuck mailer with locking ears, a double-sided tuck mailer, or a tear-strip version that opens cleanly and helps customers spot tampering.

Flute and board

E-flute keeps walls slim for lighter goods and crisp print, while B-flute adds stacking strength for heavier products. Both use natural unbleached kraft liners.

Printing

Print your logo and artwork on the outside, inside or both. Kraft suits one- and two-color designs; ask about full-color printing for detailed artwork and photography.

Finishes

Kraft is usually left uncoated for a tactile, natural feel. Ask about water-based coatings or spot details when you want a subtle sheen on part of the design.

Inserts and add-ons

Add die-cut cardboard inserts to hold bottles or jars in place, plus printed cards, tissue paper, stickers or a tear strip to finish the unboxing.

Eco options

Kraft mailers are paper-based and widely recyclable where facilities exist. Ask about recycled-content liners and water-based inks to keep the whole package paper-first.

FAQ

Custom Kraft Mailer Boxes: questions answered

Still unsure? Ask a packaging specialist.

What are kraft mailer boxes made of?

Kraft mailer boxes are made from corrugated board faced with unbleached kraft paper liners. The fluted middle layer gives cushioning and stacking strength, while the brown liner gives the natural finish. E-flute is common for lighter products and B-flute for heavier ones.

Can you print in color on kraft mailer boxes?

Yes. Kraft takes color printing, but the brown base mutes lighter shades, so dark inks and bold shapes read most clearly. For bright full-color artwork, ask about a white inner liner or a white kraft board and we will show the result on a digital proof.

Are kraft mailer boxes strong enough for shipping?

Corrugated kraft mailers are built to ship on their own without an outer carton. Strength depends on flute and size, so tell us what the product weighs and how it ships, and a specialist will recommend E-flute or B-flute for your order.

Do kraft mailer boxes need tape?

Most kraft mailers close with front locking tabs and dust flaps, so they hold shut without tape for presentation. Many brands still add a branded sticker or a strip of paper tape for carrier handling, or choose a tear-strip style for secure opening.

How do I get pricing for custom kraft mailer boxes?

Send your box dimensions, the quantity you are considering, print sides and any inserts through the quote form. A Vorex specialist replies with pricing and can help with the dieline and artwork, and you approve a digital proof before production.
