A printed box is often the first physical contact a customer has with your brand, and it is also the part of the product that is hardest to fix once it is wrong. A lid that sticks, a foil logo that flakes or a colour that drifts from the last order cannot be corrected on the shelf.
This guide is for brands, retailers and distributors who want their own printed boxes made in Asia. It sets out the decisions in the order a factory needs them: which box construction, which board, which finishes, how the insert holds the product, and how samples move from a plain mock-up to an approved production standard.
💬 Planning a new box or moving an existing one to a different factory? Send us the product, the box style you have in mind and a sample or photo, and we will look for factories in Asia that already make that construction. Tell us about your packaging.
Decide the construction first: rigid or folding
A rigid box is built from thick board wrapped in printed paper and arrives assembled or semi-assembled; a folding carton is printed and cut from one sheet and ships flat. The choice sets cost, freight volume and the factory you need.
Factories that make rigid boxes are often different from those that print folding cartons, so settle this before you ask for prices.
| Rigid (set-up) box | Folding carton | |
|---|---|---|
| Structure | Thick greyboard core, wrapped with printed or coloured paper | Single sheet of paperboard, printed, cut and creased |
| Typical uses | Gift sets, cosmetics, electronics, premium food and drink | Retail packs, supplements, small consumer goods, sleeves |
| Delivered as | Assembled, nested or as a collapsible version | Flat, glued or unglued |
| Freight | Takes up space in the container unless collapsible | Compact, many units per carton |
| Tooling | Cutting tools for board and wrap, sometimes a forming jig | One cutting die per size |
| Print area | Printed on the wrap paper, not on the board | Printed directly on the board |
Common rigid styles include a separate lid and base, a hinged lid with a magnetic closure, a drawer that slides out of a sleeve, and a book-style box. If you sell in the EU, size the box to the product too: Article 24(4) of Regulation (EU) 2025/40 requires operators who fill sales packaging to reduce empty space to the minimum needed for the packaging’s function, including product protection, by 12 February 2028. Our mailer box guide covers the separate 50 % ratio for e-commerce packaging.
Collapsible rigid boxes fold flat with a ribbon or magnet and save freight, but they need an extra assembly step at your end and the folding line must stay neat after repeated use.
Folding cartons cover tuck-end boxes, crash-lock bottoms, sleeves and trays. They are the right answer when the box is a container rather than the gift itself. If the box also has to survive a parcel network on its own, read our guide to mailer boxes for e-commerce, which covers corrugated board and transit testing.
Choose the board by what the box must do
Specify the board by grade, thickness and surface rather than by a factory’s own name for it, and ask for a swatch of the exact board before the first sample.
Quotations often say “art paper”, “white card” or “kraft” with a weight. These words mean different things in different factories, and two boards of the same weight can differ in stiffness and surface. Ask for:
- For folding cartons: the board type (for example a coated white board, a solid bleached board or an unbleached kraft board), its grammage and caliper, and whether the reverse side is white or grey.
- For rigid boxes: the greyboard thickness for the base and lid, the wrap paper type and weight, and the lining paper inside.
- For both: whether the board contains recycled fibre or comes from certified forest sources, if you intend to say so on the box.
Thicker is not always better. A thick greyboard with a heavy wrap paper can warp if the glue and drying are not controlled, and a very stiff folding board can crack along the crease if it is printed with heavy ink coverage. Tell the factory what goes in the box, its weight and how the box will be opened and closed.
If you want to print a recycled-content or forest-certification claim on the box, the factory must be able to prove it. Our article on recycled and FSC claims by market explains how to check a certificate and what the rules in each market ask for.
Keep the swatch
Keep a signed swatch of the approved board and wrap paper with the approved sample. When the factory changes paper supplier between orders, the swatch is what you compare against.
Finishes: what each one adds and where it fails
Foil stamping, embossing, spot gloss and soft-touch lamination each add a process step, a tool or a plate, and each has a typical failure you should look for on the sample.
Finishes make a box feel deliberate, but every one is another operation on the line. List the finishes on the specification with the exact area each covers.
| Finish | What it does | What to check on the sample |
|---|---|---|
| Foil stamping (hot foil) | Metallic or coloured foil pressed into the surface with a heated die | Fine lines filled in, flaking at edges, alignment with print |
| Embossing / debossing | Raises or presses the board with a matched die | Depth, sharpness, cracking of the paper surface |
| Spot UV or spot varnish | Gloss or matt coating on selected areas | Registration with the print, coating spreading beyond the area |
| Lamination (gloss, matt, soft-touch) | Thin film over the printed sheet | Bubbles, peeling at folds, scuffing, fingerprints |
| Window | Clear film behind a die-cut opening | Film wrinkles, glue marks, film material named on the spec |
| Ribbon, magnet, handle | Opening and carrying features on rigid boxes | Pull strength, magnet alignment, ribbon fixing inside |
Foil and embossing need their own dies, made for your artwork. Small text and thin lines do not foil or emboss cleanly, so ask the factory for its minimum line width and spacing before you finalise the design, and keep that guidance in the artwork file. Our guide to dielines, artwork and colour proofing sets out how to prepare a file the factory can use without redrawing it.
Lamination changes how a box can be recycled in some collection systems, and a plastic window adds a second material. If you plan any environmental statement, decide the finishes and the claim together.
💬 Not sure which finishes your box can carry without cracking or flaking? We will ask the factory for a finishes trial on your board and compare the results with you. Send us your design.
The insert holds the product, not the box
Specify the insert material, cavity sizes and tolerance against the real product, and test it with production-standard products rather than with a drawing.
Inserts keep the product in place and give the unboxing its shape. The usual materials are paperboard or folded card, moulded pulp, foam and wrapped greyboard with cut-outs.
- Send the factory real products, not only drawings. Bottles, devices and jars vary from batch to batch, and a cavity cut to the drawing can be too tight or too loose for the real item.
- State how the product is lifted out. A tight cavity looks good in a photograph and frustrates customers who cannot get the product out.
- If several items share one insert, mark each cavity on the dieline so the packing line cannot swap them.
- If the box travels inside a shipping carton, the insert still has to hold the product when the box is dropped.
Moulded pulp and paper inserts are used where a brand wants to avoid plastic foam. If you then call the box plastic-free, every component, including windows, lamination and adhesive tapes, has to support that statement.
Sample stages for a printed box
A printed box usually passes through a plain structural sample, a printed pre-production sample and a final production sample; approve each one in writing before the factory moves on.
Our general article on sample approval stages explains counter-samples and written approval. For printed boxes the stages look like this:
| Stage | What it is | What you approve |
|---|---|---|
| Structural (white) sample | Unprinted box in the specified board | Size, fit with product and insert, opening action, board stiffness |
| Digital or printed proof | Print on paper or the actual board | Artwork content, colour direction, barcode readability |
| Pre-production sample | Printed on the production press with the finishes | Colour against the standard, finishes, assembly, glue |
| Production sample | Taken from the volume run | Match to the approved pre-production sample |
Skipping the white sample saves a step and usually costs more later. Fit problems, such as a lid that is too tight or a cavity in the wrong place, show up on a plain box at a fraction of the cost of a printed one.
Keep one approved sample at the factory and one with you, both marked with the date and the approver. At pre-shipment inspection, the inspector compares the volume run against that sample for colour, finishes, dimensions and assembly.
What drives the price of a custom box
Box prices are built from the construction, board, print, finishes, insert and quantity, so the only way to compare factories is to send every factory the same specification.
Prices and minimum quantities vary by factory, region and construction. Rather than figures that only hold for one supplier, here is what moves them.
| Driver | Why it matters |
|---|---|
| Construction | Rigid boxes involve more hand assembly than folding cartons |
| Size and sheet layout | How many boxes fit on one printed sheet affects waste |
| Board and wrap paper | Grade, thickness and special papers change material cost |
| Number of colours and spot colours | Each extra colour adds plates and set-up |
| Finishes | Foil, emboss and spot coating each add a die or a pass |
| Insert | Material, cavities and assembly time |
| Number of designs | Separate artworks on the same construction each need set-up |
| Packing and delivery | Assembled rigid boxes take far more space than flat cartons |
When you collect quotations, send a written specification and, if you can, a reference sample. Compare the full delivered cost rather than the unit price alone; our article on comparing Asian suppliers on landed cost shows how.
Customs classification
For customs, cartons and boxes of paper or paperboard fall under heading 48.19 of the Harmonized System. Subheading 4819.10 covers cartons, boxes and cases of corrugated paper or paperboard, and 4819.20 covers folding cartons, boxes and cases of non-corrugated paper or paperboard. A rigid box with a magnet, ribbon or plastic window can raise classification questions, so confirm the code and the rate in the market where you import before the first shipment.
Brand protection and what we will not copy
Put your own brand on the box and keep the artwork files and dies on record; do not ask a factory to reproduce another company’s logo, character or packaging design.
Packaging designs, logos and characters belong to their owners. A box that copies a well-known brand’s look exposes the seller to claims as well as the factory. Sunsho Trade does not arrange copies of another company’s logos, characters or packaging designs.
For your own brand:
- register your trademark in the markets where you sell before the boxes are printed; our note on trademark registration before launch explains why the order matters
- agree in writing who owns the cutting dies, foil dies and embossing dies, and that the factory will not use your artwork for anyone else
- keep a master artwork file, the approved dieline and the approved sample together, so a second factory can reproduce the box if needed
Frequently asked questions
1. Should I choose a rigid box or a folding carton?
Choose a rigid box when the box is part of the gift or premium experience and a folding carton when it mainly protects and presents the product. Rigid boxes cost more to make and ship.
2. Can the factory match my existing box exactly?
It can usually get close if you send a physical sample, the original artwork files and the board specification. Colour and board can still differ slightly between factories, so approve a new pre-production sample.
3. Why does foil stamping on my logo look blurred?
Very thin lines and small gaps fill in when foil is pressed. Ask the factory for its minimum line width for foil and adjust the artwork before the die is made.
4. Do I need a separate insert for every product size?
Usually yes, because each cavity is cut to the product. A shared insert can work if the products have the same footprint, but test it with real products.
5. Can I print “recycled” or an FSC label on my box?
Only if the material and the supply chain support it. FSC labels need a certified supply chain, and recycled claims need evidence of the content. Confirm the current rule in the market where you sell.
Summary
A good printed box starts with the construction and the board, adds only the finishes the design needs, and is approved in stages from a plain sample to a production sample. Fit problems are cheapest to fix on a white sample, before anything is printed.
Sunsho Trade is a trading company, not a factory. For printed boxes we find and vet the factory in Asia that fits your construction, collect quotations on identical specifications, manage samples and inspection, and arrange delivery.
