A kraft mailer box is a corrugated shipping box made with natural brown kraft liner for a recyclable, earthy look.
Kraft liner keeps the natural fibre color instead of a bleached white face, so the box looks organic and recycles easily. The corrugated core still protects the product, and kraft takes clean one- or two-color print beautifully.
Kraft mailers suit brands built on natural, sustainable or handmade values.
Organic beauty, handmade goods, artisan food and eco apparel brands use kraft to match their values, and subscription brands use it for a warm, natural unboxing. For heavier goods, compare our custom corrugated mailer boxes.
The right kraft mailer style depends on weight, closure and reveal.
| Mailer style | Best for | Why it works |
|---|---|---|
| Roll-end tuck front (RETF) | E-commerce and subscriptions | Strong front, tape-free close |
| Self-locking mailer | High-volume shipping | Locks flat, fast assembly |
| Front-tuck mailer | Light retail items | Simple, economical |
| Die-cut mailer | Handmade and gift goods | Custom shape, natural reveal |
| Literature / book-wrap | Apparel and flat goods | Snug wrap, low DIM weight |
A roll-end tuck front suits daily shipping, while die-cut kraft mailers suit handmade gifting. For a bold dark alternative, see our custom black mailer boxes.
Kraft mailers are cut to any product, and the chart shows common sizes in inches.
| Box size (L x W x H) | Fits | Common use |
|---|---|---|
| 4 x 4 x 2 in | Soap, samples, small goods | Handmade and DTC |
| 6 x 4 x 2 in | Cosmetics, candles | Natural beauty |
| 8 x 6 x 2 in | Apparel, flat goods | Eco fashion |
| 9 x 6 x 3 in | Multi-item boxes | Subscriptions |
| 10 x 8 x 3 in | Apparel sets, kits | Retail and gifting |
We size each kraft mailer to the product so it sits snug, cutting movement in transit and keeping dimensional (DIM) weight low. Fully bespoke sizes are cut on request.
Kraft mailers use recyclable corrugated board, chosen by product weight and shipping distance.
| Board / flute | Thickness | Typical ECT | Best for |
|---|---|---|---|
| E-flute kraft | ~1.5 mm | ~32 ECT | Light retail goods up to 2 lb |
| B-flute kraft | ~3 mm | ~40-44 ECT | Standard e-commerce, 2-5 lb |
| Double-wall kraft (BC) | ~6-7 mm | ~48-51 ECT | Heavy or multi-item kits |
Edge Crush Test (ECT) rates stacking strength, so heavier goods use a higher ECT. Kraft board is naturally recyclable, and FSC-certified stock backs the eco claim with a credible chain-of-custody. We do not use thin greyboard or cardstock, because only corrugated protects in transit.
We print kraft mailers by three methods, chosen by run size and look.
| Printing method | Best for | Main strength |
|---|---|---|
| Flexographic | Large kraft runs | Best value, strong one/two-color print |
| Digital | Short runs and samples | No plates, full color on kraft |
| Offset (litho-lam) | Detailed art on a liner | Sharpest print where needed |
Kraft looks best with bold one- or two-color flexo print that keeps the natural fibre showing, while digital handles short runs and full-color designs.
| Color system | Use it for | Note |
|---|---|---|
| CMYK | Full-color art, gradients, photos | Standard four-color process print |
| PMS (Pantone) | Exact logo and brand colors | Identical shade on every reprint |
| RGB | On-screen design and previews | Convert to CMYK before printing |
Ink sits on a brown base, so colors read warmer; we build art in CMYK, match Pantone (PMS) brand colors and confirm on your proof. Our CMYK, PMS and RGB color guide explains it.
Kraft mailers use minimal, recyclable finishes that keep the natural look.
| Finish | Effect | Best for |
|---|---|---|
| Uncoated kraft | Pure natural fibre look | Maximum eco appeal |
| Water-based aqueous coating | Light scuff protection, recyclable | Everyday shipping |
| Soy-based ink | Lower-impact print | Sustainable brands |
| Kraft foil / spot UV | Selective premium accent | Gift and hero SKUs |
Most kraft mailers are left uncoated or given a water-based coating so they stay fully recyclable, with foil reserved for a hero SKU.
