Overview

About this tear-strip mailer box

A tear strip is a perforation cut into the die, positioned so that one pull separates a narrow band of board and lets the lid lift. Because it is part of the die rather than a strip of tape applied afterwards, it costs nothing to run but it does cost something to tool: this format starts at 300 pcs, and its minimum tier is our published 300 pc price band. The board, printing and inside-print options are the same as the standard mailer, so the strip is essentially a structural upgrade on an existing specification. On a printed interior it also solves a presentation problem: the customer opens the box by pulling rather than by hunting for a knife or tearing a corner, which is what makes an unboxing sequence look deliberate on camera.

It earns its cost in three situations: marketplaces and channels that require a tamper-evident pack, categories with high return rates where the opening has to prove the box was not resealed, and subscription or gifting boxes where the opening is part of the brand experience. The trade-offs are the ones buyers under-estimate. The opening is single-use — a torn strip does not close again, so a customer returning an item needs other packaging or a fresh box. The die is dedicated to your size, so changing size means paying for a new one. And because this format runs at the minimum tier, the unit price is roughly twice the 1,000 pc tier of the standard mailer: if tamper-evidence is not an actual requirement in your channel, a self-locking mailer at higher volume is the better purchase.

  • ✓Single-pull perforated strip, cut into the die rather than added as a tape
  • ✓Tamper-evident: the box cannot be closed again invisibly after opening
  • ✓A dedicated die, which is why this version starts at 300 pcs rather than a lower tier
  • ✓Inside and outside printing on the same specification as the standard mailer
  • ✓Strip position set for your size, so it tears cleanly without catching the artwork

Specification

What you are ordering

ItemDetail
Board and fluteE-flute single wall as standard; B-flute or double wall where the product needs more protection
OpeningPerforated tear strip cut into the die, positioned for your size and artwork; single-pull, tamper-evident, single-use
Size rangeAny custom size; each size requires its own die, which is why a size change is a tooling cost and not a quote amendment
PrintOne or two colours of flexo as the cheapest route; litho lamination for full-colour artwork. Inside printing quoted separately on coverage
Strip placementSet away from the printed area at the lid edge, so the tear line does not cut through the artwork or a logo
CoatingWater-based varnish, matt or gloss, to protect the print through handling; a moisture barrier is a specification change quoted as its own line
PackingSupplied flat and banded; the strip has no effect on flat-packed freight volume
MOQ300 pcs per size and print — the minimum tier at which this die runs
Lead time12–18 days after sample approval, plus 3–5 days for the sample

Variants

Tear-strip configurations

The strip is a die decision, so it is worth settling the size and the strip placement together — changing either one afterwards is new tooling.

Tear strip on the lid edge

The standard placement for a mailer: the strip runs along the lid and the box opens towards the customer. Best when the interior is printed.

Tear strip with a self-locking return

The strip opens the box and the remaining structure can still be tucked shut for storage. Trade-off: it costs a little more and is not fully resealable — it will not support a return in the same box.

Tear strip plus inside printing

The combination most subscription programmes order: the pull is the moment the branding appears. Inside print is quoted on coverage.

Tear strip in B-flute

For heavier products where the box also has to protect. Trade-off: more cost, more volume and a coarser tear line that needs a wider strip.

Standard self-locking version, same footprint

If a channel does not actually require tamper-evidence, the self-locking mailer runs on the same die footprint with no strip — cheaper per box and no dedicated tooling beyond the size.

Materials

Board, liner and coating for a clean tear

A tear strip fails for one of two reasons: the board is too thick for the perforation, or the strip is placed where the artwork stops it tearing. Both are decided at the specification stage, not at the machine.

This is not food-contact packaging as standard. If the box 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 that route instead.

OptionWhat it means
E-flute corrugated boardThe standard board for this format: the perforation tears cleanly and the printed surface stays smooth. Trade-off: less crush protection than B-flute.
B-flute corrugated boardUsed where the box has to protect a heavier product as well as open cleanly. Trade-off: a wider, blunter strip, more cost and more container volume.
Kraft or white-top linerKraft for the natural look, white-top where printed colour has to stay accurate. Trade-off: a torn kraft edge is more visible than a white one, which is either a feature or a problem depending on the design.
Water-based varnish or matt laminationProtects the print so the strip tears along the perforation rather than through a scuffed surface. Trade-off: a film lamination is more durable but adds a material to declare.
Inside printThe interior face, priced on coverage. Trade-off: another press pass, and the strip has to be placed so the tear line does not cut through it.
Recycled or FSC-certified board optionsAvailable on request where a listing or a claim requires certified fibre. Trade-off: recycled liner is slightly darker, so pale artwork reads differently.

Best for

Where a tamper-evident opening pays

Subscription boxes

The pull is the first branded moment the customer experiences, and a printed interior makes it worth watching. High repurchase keeps the die cost amortised.

Marketplace and channel-driven sellers

Where the marketplace requires a tamper-evident pack, the strip is a compliance requirement rather than a design choice.

Returns-heavy categories

Apparel and footwear in particular: a torn strip makes it obvious whether a box has been opened and resealed before the return.

Beauty, cosmetics and personal care

Products sold on trust, where a visible opening supports a premium claim and an inside print supports the brand.

Gifting and limited drops

Limited editions and gifting ranges where the opening is part of the product and the volume is fixed rather than continuous.

Sizing

Sizing, strip placement and tooling

The size and the strip are one decision. The perforation has to run along an edge that folds and tears cleanly at your board grade and size, and it has to miss your artwork; change the size and you pay for a new die. That is why we ask for the product dimensions before anything else on this format.

The indicator is quoted at the 300 pc minimum tier for this die, which is the tier our published ladder starts at. Larger quantities improve the unit price on the same structure, and the strip itself is not a per-unit variable — it is tooling plus a slightly wider board allowance.

DimensionGuidance
Reference specification22×16×8cm E-flute, printed both sides, with the tear strip — the specification the published tiers are based on
Strip positionSet at the lid edge, clear of the printed artwork. Where a logo sits across the tear line, we re-cut the die or move the artwork — the printer will not fix it later
Board thicknessE-flute tears cleanly at this size; B-flute or double wall needs a wider strip and a bigger radius, which changes the tooling again
Size changesEvery size is a dedicated die, so quote all the sizes you expect to run at once. Adding a size later means paying tooling twice
Flat-packed freightThe strip has no effect on how flat the box packs, so the inbound freight advantage of this range is unchanged

FAQ

Questions about tear-strip mailers

The strip is a tooling decision with a single-use opening. Both points are worth understanding before you order.

Why does the tear-strip version cost more per box?
Two reasons, and only one of them is the strip. The strip needs a dedicated die, and this format starts at 300 pcs, which is the minimum tier of our published ladder — so the indicative figure above is a low-volume price rather than a structural penalty. At 1,000 pcs and above, the same specification moves down the ladder towards the standard mailer band. If your volume is heading past 1,000 pcs, ask us for both tiers and compare on the same size.
Can the box be closed again after the strip is torn?
No — the opening is single-use, and that is the point. A torn strip cannot be closed invisibly, which is what makes the pack tamper-evident. If your customer needs to return the item in the same box, either order the self-locking mailer instead, or plan for a return label on a fresh mailer. We would rather tell you that now than have you discover it in your returns process.
When is a tear strip the wrong choice?
When nothing in your channel actually requires tamper-evidence. If you are buying it because it looks good in a mockup, the self-locking mailer on the same footprint will save you the die and the low-tier unit price, and the inside print will still give you the branded opening. It is also the wrong choice where the box has to protect a heavy product: a wider strip in B-flute works, but at that point an RSC with a branded inner mailer is usually the more sensible structure.
What is the minimum order and what is quoted separately?
300 pcs per size and print, which is the minimum tier this die runs at. Inside printing, litho lamination, a double-wall grade, the liner choice and any protective insert are all quoted as their own lines. The strip placement itself is part of the die, so it is not a per-unit charge — but a size change is a new die.

Other formats in this range

Corrugated Mailer BoxVolume driver

Corrugated Mailer Box

A one-piece corrugated box that closes without tape and opens without a knife, supplied flat so it costs almost nothing to ship or store. E-flute is the printed, foldable profile; B-flute is the stronger one for boxes that travel with little inside. This is the highest-repurchase line we make and one of the most competitive, so we hold a specification stable between runs — but it is a volume line with a moderate margin, and it only becomes a good one once the box carries your own artwork inside and is right-sized to the product.

Subscription Box with Printed InteriorInside 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.

Folding Carton / Retail CartonRetail shelf

Folding Carton / Retail Carton

A flat-packed cardstock carton with no flute in it: the least expensive structure we make per unit, and the one shelf space is actually built around. It suits retail and FMCG-style products that need identity and a barcode more than they need protection in transit. Be realistic about the economics — this is the most price-compressed category in packaging, artwork does the differentiating, and it is worth buying from us when it belongs to a wider packaging programme rather than as a one-off run.
