Materials

Flute grades & board construction

Flute height trades print surface against stacking strength. All boards can be white-topped (mottled or fully coated liner) for brand printing.

MaterialWeight / ThicknessBest for
E-flute (single wall)1.5mm · 3-plyThin and crisp — takes offset-quality litho lamination; ideal for mailers and retail boxes.
B-flute (single wall)3.0mm · 3-plyGood all-round stiffness and cushioning; common for canned and bottled goods.
C-flute (single wall)4.0mm · 3-plyThe standard shipping flute; best stacking economy for master cartons.
BC / EB (double wall)6–7mm · 5-plyHeavy loads, long transit, fragile goods — or when one carton must replace two.
White-top kraft linervariesMottled or clay-coated white face for flexo branding on any flute.

Edge-crush (ECT) and burst ratings specified per lane: tell us the stacked weight and shipping route and we quote the minimum board that passes drop tests.

FAQ

Common questions

Which flute should I choose for a mailer box?

E-flute is our default for branded mailers: it prints cleanly, folds sharply and keeps shipping weight low. Move to B or EB when unit weight exceeds roughly 3–5kg or transit involves multiple carriers.

Are your mailer boxes FBA-compliant?

Yes — we produce FBA-ready cartons with correct labeling surfaces, box weight limits and poly-bagging if required. Tell us your marketplace and we handle the spec sheet.

Can I get full-color printing on kraft board?

For vivid CMYK on corrugated, we recommend litho lamination (art sheet mounted to flute). Direct flexo CMYK is possible but colors will mute against the brown liner.
