Card Stock
Lighter than corrugated, card stock works for low-weight products and printed inserts. Flat surface takes high-resolution CMYK print cleanly.
Natural Kraft Board
Unbleached mix of virgin and recycled pulp with a raw brown finish. Common in natural food, organic skincare, and zero-waste product lines.
Oyster White Kraft Corrugated
Off-white linerboard with a smooth surface for sharp print detail. Sits between kraft brown and bleached white in tone.
Bleached White Board
Bright white surface for vivid CMYK output and sharp logo reproduction. Standard choice for retail packaging and branded mailers.
Kraft
Tear-resistant, recyclable brown board. Used by brands with natural, raw, or minimal visual identities.
White Kraft
White liner with a slightly softer tone than bleached board. Prints cleanly without the stark brightness of fully bleached stock.

What Makes a Box a Mailer Box?
Mailer boxes are one-piece cartons with flaps that lock into place without tape. The structure is strong enough to ship as-is, with no outer shipping box needed. Corrugated fluting or heavy paperboard provides crush resistance. Sizes are customized to the product to minimize dimensional weight and reduce shipping cost.
We produce mailer boxes in white SBS, kraft, or corrugated. Single-wall corrugated for lighter items; double-wall for heavier or fragile products. Full-color printing on exterior and interior. Matte, gloss, or soft-touch lamination. No minimum order. Production 8–10 business days. Free shipping within the continental US.
Interior Print as a Brand Asset
Mailer boxes are one of the few packaging formats where interior printing pays back reliably. Subscription, gift, and PR brands print branded artwork, thank-you messages, or customer onboarding flows on the inside surfaces, and customers photograph it. The cost premium over exterior-only is small relative to the social reach when unboxing content gets shared. Even if you do not push for unboxing content, the interior treatment changes how the box feels in the customer's hands and signals that the package was designed, not just commodity-shipped.
Built for Modern Shipping Needs
Mailer boxes are designed for efficiency and protection across all shipping scenarios.
- E-commerce and online retail stores
- Subscription box services
- Promotional kits and product samples
- Crowdfunding campaign rewards
- Direct-to-consumer brand shipments
Right-Sizing for Dimensional Weight
Couriers (USPS, UPS, FedEx, DHL) bill on whichever is greater: actual weight or dimensional weight (length × width × height ÷ a divisor). A box one size too big can double your shipping cost on the same product. We help you size mailers to your product to keep DIM weight as low as possible.
Single-Wall vs Double-Wall Decision
Single-wall corrugated handles items under ~2 lb in normal courier handling. Double-wall is for heavier products, fragile items, or anything that ships internationally and goes through more handling stages. Picking wrong on either side either wastes money or risks crush damage.
Interior Print as Brand Asset
Interior printing turns the unboxing reveal into a brand moment. Most photographed parts of a subscription unboxing on social media are interior surfaces. The cost premium over exterior-only is small relative to the marketing reach when customers post.
What can you ship in mailer boxes?
Apparel, shoes, cosmetics, electronics, books, subscription kits, promotional and PR mailers, and most D2C products that fit within typical dimensions. Items over ~2 lb usually need double-wall corrugated. Fragile items benefit from custom inserts (foam, paper, or molded pulp).
Can you print on the inside of mailer boxes?
Yes. Interior printing creates a branded reveal when the customer opens the box. Cost depends on print coverage and complexity. We quote exterior-only and full interior+exterior at the same time so you can compare. Brands posting unboxing content typically find the interior premium pays back fast.
Do mailer boxes need an outer shipping box?
No. Mailer boxes are designed to ship as-is. The structure and board weight are chosen to handle courier movement directly. Some brands add a poly outer for weather protection on long-haul or international shipments. Inside the box, void fill or inserts handle product protection if needed.
Are mailer boxes recyclable?
Yes. Cardboard, paperboard, and corrugated are all curbside-recyclable in most US municipalities. Kraft and recycled-content options carry the eco signal more visibly. Soy-based and water-based inks are available for brands building a verifiable sustainability story.
