Built on the Factory Floor, Not a Reseller Desk
Mailer Box Factory was founded to bridge the gap between industrial corrugated converters and modern growing brands. We eliminate packaging broker markups by giving brands direct access to large-scale converting machinery.
Industrial Scale Meets Custom Agility
For decades, small and mid-sized e-commerce brands were forced to purchase custom packaging through middleman brokers who added 30% to 50% surcharges simply for forwarding job orders to industrial converters.
Mailer Box Factory operates our own converting equipment, including multi-color flexographic printing presses, high-definition digital sampling tables, and high-speed rotary die-cutters. By ordering directly with us, you work with the packaging engineers who actually run your paperboard through the presses.
Why Buy Direct From the Box Factory?
Most websites selling custom mailer boxes are sales brokers or drop-shippers who outsource your order. When you partner with Mailer Box Factory, you work directly with the manufacturing facility.
