Frequently Asked Factory & Manufacturing Questions
Transparent answers on minimums, production timelines, dielines, and corrugated board specifications.
Why buy custom mailer boxes direct from Mailer Box Factory instead of a broker?
Traditional packaging websites act as brokers who mark up prices by 30-50% before outsourcing your job. Mailer Box Factory owns the converting equipment, flexographic presses, and rotary die-cutters, giving you direct wholesale rates, transparent lead times, and dedicated engineering oversight.
What is your minimum order quantity for bulk custom mailer boxes?
Our standard MOQ is 500 units per custom size and graphic version. This ensures maximum efficiency on our industrial production lines while delivering substantial per-box savings compared to on-demand digital print shops.
What corrugated flute types and burst test strengths do you offer?
We manufacture in ECT-32 and ECT-44 corrugated flutes, including ultra-smooth E-Flute (1/16") for crisp retail printing and heavy-duty B-Flute (1/8") for added stacking strength and drop protection.
How fast can I receive my custom printed mailer boxes?
Standard manufacturing turnaround is 7 to 10 business days following digital dieline proof approval. Rush orders (5 days) are available upon request.
Do you offer double-sided printing (inside and outside)?
Yes. Double-sided printing is one of our most popular capabilities for direct-to-consumer and subscription box unboxings. You can print rich flood colors, thank-you messages, and custom patterns on the inside lid and base.
