Custom Mailer Packaging Solutions for Global Brands
Mailer boxes are self-locking shipping cartons designed to protect products in transit without needing adhesive shipping tape. Engineered from premium single-wall or double-wall corrugated cardboard, our custom mailer packaging delivers maximum crush resistance for e-commerce, D2C retail, and subscription box programs.
As a direct custom packaging manufacturer, Packify Custom Boxes provides full digital and CMYK offset printing on both the exterior and interior surfaces of your boxes. Our automated dielines eliminate setup die charges, allowing overseas importers, wholesalers, and e-commerce brands to order right-sized mailers that lower dimensional weight (DIM weight) and reduce international freight expenses.
