Frequently Asked Questions — Mailer Box
▶ What is the difference between B-flute and E-flute mailer boxes?
B-flute (3.5mm) is thicker, stronger, and better for heavier products (>500g). It offers superior crush resistance for shipping. E-flute (1.5mm) is thinner and lighter — ideal for lightweight cosmetics, books, and flat items where print quality is a priority. E-flute holds sharper print detail than B-flute.
▶ Do your mailer boxes require tape to close?
No — our standard mailer boxes use a self-locking crash-lock base with dust flaps and locking tabs. No tape required. For high-volume e-commerce, we also offer peel-and-seal adhesive strips for faster packing line speed.
▶ Can I print a full-color design inside and outside?
Yes. We offer CMYK 4-color flexo printing on both exterior and interior surfaces. Interior printing is popular for unboxing experience — brand story, thank-you message, QR code, or decorative pattern. Interior print adds approximately 15-20% to unit cost.
▶ What is the minimum order for custom printed mailer boxes?
MOQ is 100 pcs for single-color flexo printing and 300 pcs for full CMYK 4-color printing. Offset litho laminated boxes (highest print quality) require 500 pcs minimum. Free structural sample before production.
▶ Are your mailer boxes ISTA certified for Amazon FBA?
Yes — our standard B-flute mailer boxes meet ISTA 2A transit testing requirements for vibration, drop, and compression. We can provide ISTA 2A test reports upon request. For Amazon FBA specifically, we recommend 32 ECT (Edge Crush Test) minimum, which all our standard boxes exceed.
