Overview

About this corrugated mailer box

The box is a single die-cut sheet of corrugated board that folds into a tray with a self-locking lid. E-flute — the thinner profile — is what nearly all printed mailers and subscription boxes are built on, because it folds cleanly around a printed surface, keeps the parcel light and takes detail better than a heavier flute. B-flute is the thicker grade, used where the box itself has to absorb handling: shipping boxes, multi-item orders, anything that gets stacked. Print method is the other half of the structure. One or two colours of flexo on kraft or white-top board is the cheapest route and holds the MOQ at 300 pcs; litho lamination gives you full-colour, photographic artwork and lifts the MOQ to 1,000 pcs, because a laminated sheet is a different production process. The 22×16×8cm spec printed both sides with a tear strip is the size and specification our published price ladder is built on.

It is the right box when you ship the same kind of thing over and over: apparel, cosmetics, accessories, small homeware, a subscription assortment. It is also the most competitive structure in this range, and we will not pretend otherwise — the competitor count is high, the unit margin is moderate, and a plain unprinted mailer is a commodity you can buy from anyone. What makes the line work is volume, very high repurchase and low freight volume. It becomes a good line rather than a cheap one at the point where the box carries your own artwork inside and is right-sized to the product. The limits are physical: a single-wall mailer is not a shipping case for something heavy or fragile, and it is not a moisture barrier unless you specify a coating or a liner.

✓E-flute for printed mailers, B-flute where the box has to survive the belt
✓Self-locking tuck as standard; tear strip where the opening has to be tamper-evident
✓Inside printing available — the surface the customer sees when the box opens
✓Supplied flat, which keeps both the inbound freight and your storage small
✓Board, print, opening and packing as separate lines you can trade between

Specification

What you are ordering

Item	Detail
Board and flute	E-flute single wall as standard (22×16×8cm reference); B-flute where the box has to protect or stack; double wall quoted separately
Format	One-piece die-cut mailer with a self-locking tuck lid; tear-strip version requires its own die

Lead time	12–18 days after sample approval, plus 3–5 days for the sample

Variants

Flute, opening and print configurations

Two decisions do most of the work here: which flute the product needs, and whether the inside of the box is printed. Both change the price materially, and both are visible in the quote as separate lines.

E-flute — the printed profile

Thin, light and the best printing surface of the flute grades, which is why it carries almost every branded mailer. Trade-off: less edge-crush strength than B-flute, so it is the wrong choice for a heavy product with no void fill.

B-flute — the protective profile

Thicker board for boxes that take handling or stack on a van shelf. Trade-off: more cost and more container volume, plus a coarser printed surface, so fine artwork suffers.

Self-locking tuck

Closes without tape and opens without a knife — the cheapest opening and the better one for anything a customer opens on a table rather than a doorstep.

Tear strip

A single-pull, tamper-evident opening that marketplaces and returns-heavy categories often ask for. Trade-off: it needs its own die, which is why the tear-strip version starts at 300 pcs, and the opening is single-use.

Inside printing

The surface the customer sees first. Priced on coverage rather than colour count, so a small logo on the base costs less than a full interior flood — and it is the cheapest way to make a mailer feel like a brand.

Single wall or double wall

Double wall is quoted as its own line for boxes that travel alone or carry weight. Trade-off: it is heavier, takes more volume, and usually means the outer carton count changes too.

Materials

Board, liner, print method and coating

On a mailer the board grade is the protection, the liner is the look, and the print method is what decides whether the artwork can do any selling. Ask for all three as separate lines and the quote becomes comparable.

These boxes are not food-contact packaging as standard. Where a mailer is used for food or cosmetics, the board, coating and ink need a specification change and the destination market's declarations — tell us at brief stage and we will quote the food-grade route instead of assuming the standard one is acceptable.

Option	What it means
E-flute corrugated board	The thinner flute and the best printing surface of the grades. Folds cleanly, keeps the parcel light. Trade-off: less protection against crushing than B-flute, so it needs either a light product or a little void fill.
B-flute corrugated board	The thicker grade, used where the box absorbs the journey. Trade-off: more cost, more container volume and a less refined print surface.
Kraft or white-top liner	Kraft gives the natural, unbleached look many D2C brands want; white-top takes colour and detail better. Trade-off: white-top costs slightly more per box and kraft changes how every printed colour reads.
Recycled or FSC-certified board options	Recycled content and certified fibre are available on request, which is often what a retail listing or a sustainability claim actually requires. Trade-off: recycled liner is slightly darker and less uniform, so pale print reads differently.
One or two colour flexo print	The cheapest print route and the reason the MOQ sits at 300 pcs. Trade-off: it suits logos, line work and type, not photographs or gradients.
Litho lamination	A printed sheet laminated to the corrugated board for full-colour, high-detail artwork. Trade-off: it lifts the MOQ to 1,000 pcs and costs more per box, and it is only worth it when the artwork is doing commercial work.
Varnish, matt or gloss water-based coating	Protects the print through handling and scuffing and changes how the box feels. Trade-off: a film lamination is more durable but is another material to declare, so water-based is the default on this range.

Best for

Who reorders a corrugated mailer

D2C apparel and accessories

Light, low-value-density products shipped one at a time. E-flute is enough, the box prints well and right-sizing cuts dimensional weight on every parcel.

Beauty, skincare and fragrance

The category where inside printing pays for itself: the box is opened on camera and the interior is the first thing seen. A printed insert or tissue is quoted as its own line.

Subscription programmes

High repurchase volume with a fixed monthly size, which is exactly what this line is built for. Consistency between runs matters more than the last cent of unit price.

Consumer electronics and small homeware

Heavier items where B-flute or double wall earns its cost, usually with a protective insert. Send the product weight and the drop risk and we will recommend the grade.

Marketplace and social sellers

Sellers who ship through marketplaces where the box is also the packaging the customer keeps. Tear-strip and labelling requirements are usually set by the channel.

Hampers and gift sets

Multi-item orders where the mailer carries the branding and a board divider keeps components apart — the divider is quoted separately.

Sizing

Right-sizing, dimensional weight and flat-packed freight

Carriers bill dimensional weight, so empty volume inside a mailer is a charge you pay on every single shipment. Taking two centimetres out of the height of a mailer across a thousand units usually saves more than anything you can negotiate off the unit price — and it reduces your pallet footprint on the inbound leg at the same time. Give us the product's dimensions and how you pack it, and we will show both the size you asked for and a right-sized version.

The indicator above is quoted at the 1,000 pc tier for a 22×16×8cm E-flute mailer printed both sides with a tear strip, which is the specification the published ladder in this range is built on. Different sizes, flutes and print methods are quoted per specification, and there is one more lever worth knowing about: the number of size SKUs. Every extra size splits the same order across more die lines and pushes all of them down the volume ladder.

Dimension	Guidance
Reference size	22×16×8cm, E-flute, printed both sides with a tear strip — the specification the published price tiers are based on
Product clearance	Product dimensions plus the void fill you actually use, plus 3mm clearance. A box that is tight against a printed interior scuffs in transit
Dimensional weight	Empty height is the most expensive thing you can ship. Measure a packed parcel against the carrier's divisor before you approve a size — it is usually worth more than a few cents off the unit price
Number of sizes	Every extra size is another die and a smaller quantity per die line, which pushes every size down the ladder. Three sizes cost more than one, and not only because there are three of them
Flat-packed freight	Mailers ship and store flat as standard, so the inbound volume is a fraction of assembled boxes. That is the main landed-cost argument for this structure

FAQ

Before you order a mailer box

This is a competitive line, so the numbers matter more than the adjectives. Here is where the money actually goes.

Is there real money in mailer boxes?

Be clear-eyed about it: mailers are the most competitive structure we make, the competitor count is high and the unit margin is moderate rather than generous. What makes the line work is volume, very high repurchase and low freight volume, because the boxes ship flat. It becomes a good line rather than a cheap one the moment the box carries your own artwork inside and is right-sized to the product. If you need margin per unit rather than margin per order, the rigid gift box and food-grade ranges are the better conversation.

E-flute or B-flute — which should I order?

It depends on what is inside and how the box travels. E-flute is thinner: it folds cleanly, prints with a smoother surface and keeps the parcel light, which is why printed mailers and subscription boxes are built on it. B-flute is heavier, for boxes that have to survive a sorting belt with almost nothing inside or that get stacked — shipping boxes and multi-item orders. Send us the product weight and packing method and we will recommend rather than upsell.

When is a mailer the wrong choice?

Three cases. If your product is heavy or fragile enough to need a shipping case, a single-wall mailer is not that case — use an RSC in double wall with the mailer inside. If you need moisture protection, this is a specification change and not something the standard board does. And if you are buying at a few hundred pieces a year for one size, the economy of this line will not reach you: plan from the 300 pc tier and expect the unit price to look more like a gift box than a shipping box.

Can the box be printed inside and out?

Yes, and on e-commerce packaging the inside print is what the customer actually sees when the box opens. It is a separate pass through the press, so it is quoted on coverage — a single colour over the whole interior costs more than a small logo on the base. Inside printing is also the cheapest way to make a mailer feel like a brand rather than a parcel, which is the entire argument for paying for it.

What is the minimum order, and what is quoted separately?

300 pcs per size and print. The tear strip, inside printing, litho lamination, a double-wall grade and any protective insert are each quoted as their own line, so you can see what each decision costs and drop the ones that are not earning their money. That structure is deliberate: a mailer quote that arrives as one blended number usually hides a specification you did not ask for.

Other formats in this range

Tamper-evident

Tear-Strip Mailer Box

A corrugated mailer with a perforated tear strip built into the die, which gives the customer a single-pull opening and gives you a tamper-evident pack. Marketplaces, returns-heavy categories and subscription programmes ask for it, and it is the opening that makes an unboxing video look deliberate. The trade-off is honest: the strip needs its own die, the unit cost is higher than the self-locking version, and the opening is single-use — once it is torn, the box does not close again.

Inside print

Subscription Box with Printed Interior

A corrugated mailer built the way a brand product is built: full-colour litho-laminated artwork outside and inside, a printed insert card, and a size that matches the assortment rather than a stock carton. The interior print is the reason to buy it — it is the surface the customer photographs when the box opens, and it is the single cheapest thing that turns a parcel into a brand. The honest trade-off is the MOQ: litho lamination starts at 1,000 pcs, so this is a format for a programme, not a first test order.

Landed cost

RSC Shipping Box

The cheapest box in this range and the least glamorous: a regular slotted container that gets your order to a fulfilment centre or a customer intact. It is bought for protection and dimensional weight, not for unboxing, and right-sizing it to your product and your pallet is usually worth more than any negotiation on the unit price. This is not a customer-facing box — if the customer sees the packaging, use a branded mailer inside it or instead of it.
