Custom Crash Lock Bottom Corrugated Mailer Box for Clothing and Shoes
This box does the unglamorous work of e-commerce: shipped flat, folded in seconds, strong enough to arrive intact. This corrugated mailer box — commonly called a crash lock bottom or airplane box — is a one-piece folding carton with an automatic lock bottom that snaps into place as you fold the sides, plus top tuck flaps for secure closure.
It is made from recyclable corrugated board that is widely accepted in paper recycling programs, and it can be printed with your own brand logo so the box doubles as the outer shipping package. For apparel, footwear, and subscription deliveries, that removes a packing step and a layer of material at once.
Crash Lock Bottom: Faster Packing, No Tape at the Base
The automatic crash lock bottom locks into place instantly when the sides are folded. No tape or glue is required to assemble the base. Compared with a standard RSC box, the crash lock structure removes a taping operation from every single order — a difference that compounds quickly during peak season.
The top closes with tuck flaps that fold and secure in place. Seal the top with tape or an adhesive sticker for a tamper-evident finish, or leave it unsealed so the customer opens the package easily. Either way, boxes arrive flat-packed and pop open in seconds, and flat bundles take up far less warehouse space than pre-assembled cartons.

Use Cases
E-commerce shipments. Apparel, accessories, small electronics, books, and cosmetics all ship well in this construction, and the box carries the brand surface directly.
Subscription boxes. Monthly delivery programs for beauty, snacks, or lifestyle products benefit from the fast assembly.
Retail packaging. Brick-and-mortar stores can use it as a take-home box that keeps the brand in the customer's hands after purchase.
Food delivery. Bakery items, meal kits, and dry goods can be packed with a food-safe liner specified as an option.
Product launches. Direct-to-consumer brands can use custom printed mailers to build a branded unboxing experience without an outer carton.
Branding Options
Printing is available in two practical routes. Flexographic printing covers one to three colors and suits high-volume runs with a straightforward brand mark or pattern. Digital printing produces full-color CMYK artwork, which suits detailed illustrations or campaigns that change frequently.
Beyond printing, the box can be customized with a window cutout covered by film, inner dividers to separate multiple items, or finishing treatments such as matte lamination, aqueous coating, embossing, or soft-touch film. Because the box carries your print on its exterior, no additional shipping carton is needed.
