Custom Corrugated Mailer Boxes for E-commerce

Custom corrugated mailer boxes from Colormix in Guangzhou, China: 500 pcs per size, digital samples in 3–7 days; production-line samples in 7–10 days, bulk in 15–22 working days after approval. Each mailer is sized around the packed product, with flute grade, opening style and insert matched to the weight and the courier route. It ships flat and is assembled at packing, so storage takes a fraction of the delivery volume.

A mailer box is the shipping carton that doubles as the unboxing. It has to protect the product in transit, open without a knife, and still look like the brand when it lands. We match flute grade, opening style and insert to the product weight and the route it travels.

Corrugated Mailer Boxes: the structures we quote most

Each structure changes the dieline, the assembly time and the unit cost. Send the product and we quote the two that fit, rather than all of them.

Board and materials

  • E-flute corrugated
  • B-flute corrugated
  • BC double-wall corrugated
  • White-top kraft corrugated
  • Recycled kraft corrugated

Finishing

  • Flexo printing for large runs
  • Digital printing for short runs
  • Litho-laminated top sheet
  • Matte varnish
  • Interior print

Inserts

  • Corrugated fitment
  • Die-cut EVA foam
  • Paperboard platform
  • Molded pulp insert
  • Honeycomb paper wrap

Material and finish are specified per project and confirmed on the sample. Where a material claim matters — recycled content, plastic-free insert — the specification states what the material is, so the claim can be checked rather than assumed.

Corrugated Mailer Boxes: questions before ordering

Which flute should I use?

It depends on product weight, fragile parts and the shipping route. E-flute is typical for light retail goods, B-flute for mid-weight, and double wall for heavy or long-distance shipments. We recommend one after seeing the product and its packed weight.

Can the mailer be printed on the inside?

Yes. One-colour interior print is common for a short message or a return instruction, and it costs far less than full-colour interior coverage.

Will the box survive international courier handling?

Flute grade, corner clearance and insert design are set for the route. For multi-leg shipments we test the packed weight against the board grade before quoting.

What is the minimum order?

500 pcs per size.
