Custom mailer box styles: roll-end, tuck-top and shipping boxes

The roll-end mailer is the familiar e-commerce box: a single piece with double side walls that fold in, a lid that tucks into the front, and a clean presentation when it is opened. It suits clothing, cosmetics, accessories and subscription boxes. Tuck-top mailers are a simpler construction and often a little more economical for lighter products. Plain shipping boxes are built for protection and stacking rather than presentation, and display trays go from transport straight onto a retail shelf.

  • Branded unboxing and subscriptions: roll-end mailer
  • Lighter products with a cost focus: tuck-top mailer
  • Heavier goods and outer packs: shipping box, usually in B-flute
  • Retail-ready presentation: display tray

E-flute, F-flute or B-flute: choosing corrugated board

Flute size balances print quality, strength and thickness. F-flute is the thinnest and gives the finest print surface, so it suits small, premium mailers. E-flute is the usual choice for e-commerce: thin enough for crisp folds and good print, yet strong enough for the post. B-flute is thicker and better at absorbing knocks and carrying weight, so it is typically used for heavier products and outer shipping boxes.

White liners give brighter colours and a clean look; kraft liners give a natural appearance and tend to hide scuffs from handling.

Litho-lamination, inside printing and inserts

With litho-lamination, the design is printed by offset on a sheet of paper that is then laminated onto the corrugated board. This gives photographic detail and solid colours close to those of a printed folding carton. Printing the inside of a mailer makes the opening moment part of the brand, often with a pattern, a thank-you message or care instructions.

Tear strips let customers open the box without a knife. Inserts hold products in position so they do not move or rub during delivery, which is especially useful for glass, electronics and multi-item kits.

FAQ

Frequently asked questions

01What is the difference between E-flute and B-flute?

E-flute is thinner (about 1.5 mm) with a smoother print surface — ideal for mailers. B-flute (about 3 mm) is stronger for heavier shipping.

02Can the inside be printed?

Yes, inside printing adds a memorable unboxing moment.

03What is the minimum order for custom mailer boxes?

It is flexible and depends on the size and printing. Share your quantities per size and we will suggest a practical starting point.

04Will a mailer box survive courier delivery without an outer carton?

Many E-flute mailers are designed to ship on their own, but it depends on the weight, the fragility of the product and the route. Tell us how your parcels travel and we will recommend the flute and whether an insert is needed.

05Can we test a sample mailer first?

A sample or prototype can be discussed before production, so you can check the fit and run a test shipment with your own product.

06Are mailer boxes delivered flat, and do you ship abroad?

Mailers are usually delivered flat and folded at packing, which saves freight and storage space. We arrange delivery to your country, and Incoterms such as EXW or DAP can be discussed with your quote.
