Why Choose Our Mailer Boxes
Custom Mailer Boxes | Branded E-Commerce & Subscription Box Packaging
Custom mailer boxes have become the defining packaging format of the e-commerce era — the box that arrives at the customer's door carrying not just a product but an entire brand experience. Unlike plain brown shipping boxes, custom mailer boxes turn every delivery into a marketing moment, with full-color exterior printing that creates excitement before the box is even opened and thoughtfully designed interiors that make unboxing a shareable event.
Construction
Mailer boxes are manufactured from E-flute corrugated board — a thin, strong flute that provides shipping protection while offering a smooth surface for high-quality printing. The self-locking tuck closure eliminates the need for tape, creating a clean opening experience. Double-wall construction is available for heavier products requiring additional protection.
Printing Quality
E-flute mailer boxes are printed using digital printing for short-run orders (100–500 units) or flexographic printing for longer runs. Litho-lamination — applying an offset-printed sheet to the corrugated board — achieves near-photographic print quality for brands where unboxing presentation is paramount.
Interior Design
The interior of a mailer box is as important as the exterior for the unboxing experience. Options include full interior printing with brand patterns, quotes, or product photography; custom printed tissue paper inserts; foam or custom corrugated inserts to secure products; and printed belly bands or thank-you cards to complete the experience.
Why Custom Mailer Boxes Drive Brand Loyalty
Research consistently shows that premium unboxing experiences increase customer retention rates and drive social media sharing. When a customer receives a thoughtfully designed custom mailer box — full-color exterior, printed interior, branded tissue paper — they're more likely to photograph it, share it, and return for repeat purchases. For subscription box brands, the mailer box IS the product experience. Its design directly impacts subscriber retention.
Choosing Between Digital and Litho-Laminated Mailer Boxes
Digital printing is ideal for orders of 100–500 units, offering fast turnaround without tooling costs and the ability to print variable data or personalized content. Flexographic printing becomes cost-effective at 500+ units for standard designs. Litho-lamination — the premium option — applies a high-resolution lithographed sheet to E-flute board, achieving near-offset print quality with the sharpness and color saturation that digital printing on raw corrugated cannot match. For brands where the unboxing moment is a marketing strategy, litho-lam is the right choice.

Mailer Boxes in El Monte — FAQs
What is the minimum order for custom mailer boxes?
Our minimum order is 100 units. Digital printing makes short-run custom mailer boxes economical without sacrificing print quality.
Do mailer boxes need tape to close?
No. Mailer boxes use a self-locking tuck closure that secures without tape, creating a cleaner opening experience. The closure is strong enough for standard e-commerce shipping when correctly sized for the product.
Can I print the inside of the mailer box?
Yes. Interior printing is one of the most impactful elements of the unboxing experience. We print full CMYK color on the interior with brand patterns, messages, product photography, or social media call-to-actions.
What is the difference between a mailer box and a shipping box?
A mailer box is a self-contained retail-quality packaging solution with full-color printing and self-locking closure, designed to be the primary packaging a customer receives. A shipping box is a plain or simply branded corrugated box used as an outer shipper over retail-packaged products. Mailer boxes eliminate the need for a separate outer shipper for most e-commerce applications.
