Cardboard Document Mailers built to your specification — your dimensions, your board, your print.
No obligation
Name, email, phone and what you are packing and how it ships. Attach artwork if you have it. We reply with a specification and a written price, usually within one business day.
The closure is the weak point — a board mailer that opens in transit exposes the contents entirely.
If the contents are confidential, the closure needs a tamper-evident seal rather than a tuck.
Cardboard Document Mailers hold documents where a board construction gives more rigidity than an envelope. That is the starting point for the specification, because if the contents are confidential, the closure needs a tamper-evident seal rather than a tuck.
In service they are used for despatch of contracts, certificates and records where both flatness and security matter.
Cardboard Document Mailers are specified for despatch of contracts, certificates and records where both flatness and security matter. If the contents are confidential, the closure needs a tamper-evident seal rather than a tuck.
Where a product needs to be held still, a fitted insert cut to its profile does more for damage rates than a heavier outer board. It usually costs less too, because you can drop a grade on the outer.
Rigid board or E-flute with a peel-and-seal or tamper-evident closure where confidentiality applies.
The options we would consider for this format are below; if the contents are confidential, the closure needs a tamper-evident seal rather than a tuck.
A4 and US Letter footprints predominantly, with a shallow depth for a modest document count.
Send the contents rather than a box size. Board construction is chosen for rigidity and then closed with a simple tuck, which is not secure enough for confidential contents.
Mailers arrive flat and score-folded, ready to assemble by hand in a few seconds each.
Delivery windows are confirmed in writing when your order moves into production, and we flag any risk to the date before you approve rather than after.
Four things drive a quote more than anything else: the quantity, the print route, the board grade and the number of finishing passes. Dimensions matter too, but usually through how efficiently the shape nests on the press sheet.
Prices start from $0.30 per piece for large-volume orders. If a cheaper route exists we say so at quoting rather than after the invoice.
Send the product dimensions, the quantity and your deadline. What comes back is a board grade, a structure, a print method, a lead time and a written price — not a number on its own.
We send a dieline sized to your product, check your artwork and issue a proof. For shipping formats we will also flag it if the pack looks a size larger than it needs to be.
Ask for an unprinted sample if the question is fit, or a printed prototype if the question is colour. They answer different things.
Sample costs are normally credited against the production order.

Answers
Specification, minimums and lead times for cardboard document mailers.
Yes — a peel-and-seal closure or an applied security seal both show interference. A plain tuck closure does not, which matters if the contents are confidential.
Measure the product rather than the box currently in use. Most operations we quote are running at least one size too large with void fill compensating, and dropping a band saves on every parcel cardboard document mailers carry.
That is a brand decision, not a cost or protection one. For direct-to-consumer parcels where the customer opens it, print can be worth it. For business deliveries it usually is not.
Only if boxes are arriving crushed. If they arrive intact with damaged contents, the product is moving inside and a heavier outer changes nothing. A fitted insert solves that case, usually at lower cost.
Yes, and for cardboard document mailers we prefer to specify both together. A cavity that holds the contents still often lets us drop a grade on the outer, so the pair can cost less than an over-specified box alone.
Prices start from $0.30 per piece for large-volume orders. For this format the biggest levers are quantity, print route, board grade and how many finishing passes are involved. We quote each element separately so you can see where the money is going. An insert often lowers the total rather than raising it, because holding the contents still lets us drop a grade on the outer.
Yes. We can send a plain unprinted sample so you can check the fit and structure, or a printed prototype for colour and finish. Sample costs are normally credited against the production order. On cardboard document mailers the thing to check is whether the contents still sit tight once the pack is closed, because movement inside is what causes damage rather than the board grade.
Send the current specification or a physical sample and we will quote to match it rather than proposing an alternative you would then have to re-approve internally. A physical sample tells us more than a specification sheet — board caliper and coating are usually described loosely and measured exactly.
All 50 US states, the United Kingdom, Canada and Australia, on the same timeline everywhere: 3 to 5 business days of production after artwork approval, then 5 to 7 business days in transit. Every run is made to order and shipped directly to your address rather than pulled from stock, so you receive current production rather than whatever has been sitting in a warehouse. Freight is costed separately by weight, volume and destination. If you are shipping to a fulfilment centre rather than your own address, send their receiving requirements with the order — pallet height and labelling rules are usually fixed and refusals are expensive.
Every run is cut to your dimensions — there are no stock sizes here. Send the product measurements rather than a box size and we will build the mailer box around them, then send a dieline template you can design onto.
We issue a dieline template sized to your product, prepress checks your artwork against it, and a proof comes back for sign-off. Nothing runs until you approve that proof, and mailer boxes then take 3 to 5 business days.
Yes. Once a first run is approved we hold the board, structure, dimensions, print method and finishes against your account, so a reorder references the same specification exactly rather than being re-derived. It also means a reorder can be priced against a larger quantity without re-opening the specification.
