What Are Custom Kraft Mailer Boxes?

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 colour 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-colour print beautifully.

Which Brands Use Kraft Mailers

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.

Which Kraft Mailer Style Fits Your Product?

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 Mailer Box Sizes

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 Board and Strength

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.

Printing Methods on Kraft

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-colour print
Digital	Short runs and samples	No plates, full colour on kraft
Offset (litho-lam)	Detailed art on a liner	Sharpest print where needed

Kraft looks best with bold one- or two-colour flexo print that keeps the natural fibre showing, while digital handles short runs and full-colour designs.

Colour system	Use it for	Note
CMYK	Full-colour art, gradients, photos	Standard four-colour process print
PMS (Pantone)	Exact logo and brand colours	Identical shade on every reprint
RGB	On-screen design and previews	Convert to CMYK before printing

Ink sits on a brown base, so colours read warmer; we build art in CMYK, match Pantone (PMS) brand colours and confirm on your proof. Our CMYK, PMS and RGB colour guide explains it.

Eco Finishes and Coatings

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. Ready to build yours? Get a free quote and a free 3D proof now – email sales@apexiopackaging.com or call +1 (855) 466-6990.

Inserts and Add-Ons

Recyclable inserts hold products in place and complete a natural unboxing.

Insert / add-on	What it does	Best for
Corrugated dividers	Separates multiple items	Kits and sets
Molded pulp tray	Recyclable fitted hold	Eco-conscious brands
Kraft crinkle / paper fill	Natural cushioning	Fragile handmade goods
Inside printing	Branded interior reveal	Every branded shipment

Molded pulp and corrugated dividers keep the whole pack recyclable, while inside printing turns the lid into a branded moment. For small luxury goods, see our custom jewelry mailer boxes.

Built for E-commerce Shipping

Kraft mailers are engineered for the parcel network while cutting packaging waste. A right-sized kraft mailer protects against drops and stacking, removes rattle and keeps dimensional weight low, so you cut damage claims, shipping cost and material use at once. The natural finish reinforces an eco brand at the doorstep. Explore every structure on our custom mailer boxes hub.

Our Quality Review Before Production

We check every kraft mailer for board strength, fit, print and fold before it ships. We confirm flute alignment, ECT rating, print clarity on the brown base and score strength, and for heavier shipments we validate the build against ASTM D4169 distribution testing. Kraft is recyclable and tough, but if you need a rigid gift box we will say so honestly.
