Mailer Boxes

Durable Materials

Our mailer boxes are constructed from new double wall corrugated cardboard made from 3 layers of high-quality paper & fluting. This ensures superior strength and protection for your packaged contents through transportation and final delivery.

Telescoping Box Sizes

Choose from our stock of single wall mailers available in standard sizes or get boxes custom made to fit your products precisely with no extra room using our telescoping technology. This allows multiple box dimensions under one style number for simplicity.

Side Loading or End Opening Mailer Boxes

Select whether you need open ends for easy content sliding & visual access or broad side openings for stacking strength, reinforced flaps and easy label visibility during fulfillment and in transit. Most sizes are available in either style.

Water-Resistant Barriers

For an additional moisture barrier, add a water-activated tape seal to the seams as well as water-resistant coatings or laminates to the interior or exterior sides. This protects contents from rain or wet delivery truck floors.

Cushioning for Fragile Items

Protect delicate items through the shipping journey with custom die-cut cushioning inserts fitted inside your mailer boxes. Made from corrugated cardboard, EPE foam, bubble wrap or more, inserts cradle & pad individual items or sections.

Reinforced Box Materials

For heavy products, select from our range of additional strength enhancers like anti-burst hexagonal fluting which improves compression & stacking, burst-proof plus fluting with added resistance or triple wall for very heavy goods

Brand Exposure Options

Get your business details & messaging on the outside of your mailers with custom printing in spot colors or full color images, logos & text. Display return address info, marketing slogans, shipping instructions, warnings & more.

Fast Production & Delivery

We can produce single, full or multi-color logo printed side & end load regular slotted mailer boxes in quantities from 25 to tens of thousands. Benefit from 12+ years of box manufacturing experience combined with high-capacity equipment.

Assembly and Sealing

Get your mailer boxes flat-packed for easy storage and lower shipping costs, or choose to have them delivered assembled and sealed with packaging tape or glue for convenience. We also offer automated folding and sealing of assembled mailers at high speeds.

Custom Size Inserts

For an extra layer of protection, add die-cut cardboard inserts that immobilize products and prevent damage from shifting during transit. Inserts can be custom sized to grip items tightly or separate compartments.

Plastic Viewing Windows

Clear plastic viewing windows are another option allowing visual access and light exposure to box contents. Windows help showcase products without compromising the structural integrity of the mailer.

Custom Graphic Wrap Printing

For high visual impact, customized graphic art can be printed around the entire exterior surface of mailer boxes with colorful themes, patterns and photographic imagery that promote brand awareness.

Available Industry Formats

In addition to our custom mailers, various common envelope sizes and formats used by USPS, FedEx, DHL and other carriers are kept in stock ready for fast delivery to meet industry cargo standards.

Conclusion

With durable cardboard materials including enhanced triple wall layers, reinforced flaps, telescoping and adjustable sizing, side or end openings, waterproofing barriers and custom print branding, our mailer boxes deliver proven protection for your commercial or industrial contents in transit while showing off your brand.
