Key Takeaway
Australian ecommerce brands sourcing corrugated boxes generally choose between local converters with short freight lead times and overseas manufacturers with lower unit costs at volume. Teal Packaging is a US manufacturer shipping custom corrugated worldwide, with full-color print, free dieline design, and volume pricing from about $0.44 per unit at scale. A single order can carry up to 24 separate designs, useful for multi-SKU catalogues. Production runs from about 7 business days after proof approval, with rush by air and cost saver by sea. Runs start at 50 units.

Judge a corrugated supplier on four things: whether the quote names a flute and an edge crush rating, whether the die charge is stated separately, what the sample policy is, and what the stated dimension tolerance is. A quote that says only "custom box, printed, 1000 pieces" cannot be compared against anything, and comparing quotes is the entire point.
What a corrugated quote should contain
| Ask this | A usable answer | Warning sign |
|---|---|---|
| Which flute and what ECT? | 32 ECT E flute, or 44 ECT BC double wall | "Standard corrugated" |
| Are these inside or outside dimensions? | Inside, stated as length by width by depth | No answer, or dimensions with no order |
| What is the die charge and is it reusable? | A separate line, reusable on reorders | Bundled into the unit price with no detail |
| Which print method? | Flexo, digital, or litho lamination, named | "Full color printing" |
| What is the dimension tolerance? | A stated figure, commonly about 1/16 in | Silence |
| Can I have a sample before the run? | Yes, structural or printed, priced | Production only, no sample |
| What are the freight terms? | Stated up front, included or itemized | Added after you approve the proof |
Flute and strength, in plain numbers
| Board | Wall thickness | Common rating | Typical use |
|---|---|---|---|
| F flute | 1/32 in | Light | Small retail boxes with fine print |
| E flute | 1/16 in | 32 ECT | Mailers, subscription boxes, light shippers |
| B flute | 1/8 in | 32 ECT | Shippers that stack, pizza boxes, trays |
| C flute | 11/64 in | 32 to 44 ECT | General purpose shipping cases |
| BC double wall | About 1/4 in | 48 to 55 ECT | Heavy cases and long transit routes |
| EB double wall | About 3/16 in | 44 ECT | Print quality plus extra strength |
Older specifications use burst strength instead. As a rough conversion, 200 pound burst corresponds to 32 ECT, 275 pound to 44 ECT, and 350 pound to 55 ECT. Edge crush is the more useful measure for stacking, since that is the load a box actually carries on a pallet.
When custom printed corrugated is the wrong purchase
If you ship mixed orders in a plain brown box that gets recycled on arrival, stock corrugated from a local supplier is cheaper than anything custom, and no amount of design changes that. Custom printed corrugated earns its cost in three situations: when the box is the unboxing experience, when the size saves enough dimensional weight to pay for itself, and when the box goes on a retail shelf.
- Cheapest total cost usually means a plain stock shipper plus printed tape.
- Best cost per impression usually means a custom mailer with interior print.
- Lowest freight usually means a custom size, since stock sizes force you to ship air.
Print methods and what they really look like
Flexo prints directly onto the corrugated in one to three colors at a coarse line screen. Logos, solid blocks, and type look sharp. Photographs do not. Digital printing covers full color with no plates and suits short runs or many artwork versions. Litho lamination bonds an offset printed sheet to the board and is the only route to photographic quality on a shipper, at a cost that needs volume to justify.
Washboarding is the other thing to ask about. Heavy ink over corrugated can show the flute lines through the print, more visibly on B and C flute than on E flute. If your artwork has large flat solids, ask which flute the supplier recommends for it.
Comparing two quotes that look identical
Two suppliers quoting the same box at the same price are rarely selling the same thing. Line the quotes up against five fields and the differences appear immediately.
- Board. One may be quoting 32 ECT E flute and the other a lighter unrated board that costs less to make.
- Dimensions. Confirm both are inside measurements. An outside quote on a B flute box loses you a quarter inch of interior space.
- Colors. Two spot colors and full color digital are different jobs at the same description.
- Tooling. A die charge buried in the unit price makes the first order look cheap and the reorder look expensive.
- Freight. A quote that excludes shipping can land well above one that includes it.
Minimums, samples, and what you should get free
Custom corrugated starts at 50 units. Before committing to a large run, ask for a structural sample in the actual board so you can pack a real product into it and drop it. A supplier that will not produce one is asking you to buy a size on faith. Dieline drawing should be included at no charge, and a digital proof should arrive before anything prints. US shipping is included on custom orders here, and the $19.99 sample kit is credited against your first order.
| Quantity | Print route | What to negotiate |
|---|---|---|
| 50 to 250 | Digital | A sample in production board |
| 500 to 2,000 | Digital or flexo | Die charge shown separately |
| 5,000 to 20,000 | Flexo or litho lamination | Dimension flexibility for better sheet yield |
| 25,000 and up | Litho lamination | Staged delivery, from about $0.44 per unit at volume |
Lead times to plan around
Eligible in house corrugated work may run in about 7 business days once the proof is approved, and specialty imported production may take about 12 weeks. Both are planning ranges rather than promises. Teal is a US company with two production facilities, West Chicago, Illinois and Guangzhou, and corrugated jobs are routed to whichever line matches the board and the deadline.
Come to the conversation with inside dimensions, packed weight, flute preference, print method, and quantity, and every quote you collect will be comparable. Structures are listed on the corrugated box range, the shipping box page, and the subscription box page.
