Mailer Boxes
Custom corrugated mailer boxes for e-commerce. Tuck-top, mailer, and shipping designs.
What Are Mailer Boxes and Why Do E-commerce Brands Need Them?
Custom Mailer Boxes from a direct factory is a wonderful job. A mailer box (also called a shipping box or e-commerce box) is a corrugated cardboard format designed for direct-to-customer shipping. Unlike plain brown shipping boxes, branded mailer boxes turn every delivery into a brand experience — custom printing, tear strips for easy opening, and interior printing create a memorable first impression. Mailer boxes come in roll-end tuck front (RETF), tuck-top, and snap-lock bottom formats, with single-wall (3-ply) for lightweight items and double-wall (5-ply) for fragile products.
