Corrugated Mailer Boxes

Key Takeaway

Corrugated mailer boxes are self-locking, one-piece shipping boxes made from durable corrugated cardboard, designed to fold flat for storage and assemble quickly without tape. They are ideal for e-commerce brands shipping apparel, small goods, or subscription items directly to customers, since sturdy walls protect contents in transit while keeping shipping weight low. Teal Packaging manufactures these boxes with full-color custom printing on the exterior, turning every shipment into a branded unboxing moment instead of plain, generic cardboard. Ordering starts at just 50 units, with pricing from $0.44 per unit at higher volumes, making custom branding accessible for small businesses and startups, not only large retailers. Every order includes a free dieline design built to exact product dimensions plus a digital proof for review before production begins. Production typically starts about 7 business days after proof approval, with complex or high-volume orders taking longer, and Teal ships completed orders free anywhere in the US.
