Choose gift box materials in this order: structure first, then board weight (GSM), then face material, then finishing — with colour held to ΔE ≤ 2 and dimensions to ±0.5 mm.
Most buyers work backwards, picking a finish they liked on another project and forcing it onto a structure it does not suit. The four decisions below are sequential, and each one narrows the next.
Step 1: Decide the structure
Structure sets everything downstream — the tooling, the assembly method and the price floor.
| Structure | Core material | Best for |
|---|---|---|
| Rigid gift box | Greyboard 1–3 mm | Luxury, keepsake, display |
| Folding carton | Paperboard (C1S/SBS) | Retail, ships flat, low cost |
| Corrugated mailer | Corrugated board | Shipping, e-commerce |
If the box must survive shipping as well as look good on a shelf, a rigid box with a corrugated outer sleeve is the common hybrid.
Step 2: Choose the board weight (GSM)
GSM — grams per square metre — controls stiffness, cost and how cleanly the box folds.
| Element | GSM | Notes |
|---|---|---|
| Greyboard core | 1400 gsm | 1–3 mm; heavier for large lids |
| Rigid box face paper | 143 gsm | Thin so it wraps corners without cracking |
| Folding carton body | 300 gsm | Stiff enough to stand, thin enough to fold |
| Insert / tray board | 375 gsm | Holds product without collapsing |
Higher GSM is not automatically better: over-heavy board cracks along crease lines if the creasing matrix is not adjusted. We set a written tolerance of ±5% of the specified GSM (per ISO 536) so the mill and the press are measured against the same number. For a deeper dive, read our GSM guide for packaging paper.
Step 3: Pick the face material
| Face material | Use | Cost |
|---|---|---|
| Art paper (coated) | Retail boxes, sharp graphics | Medium |
| Kraft (uncoated) | Eco gifting, natural look | Low |
| Specialty (textured, metallic, soft-touch) | Premium, limited editions | High |
Coating changes how the same graphics read: art paper gives bright, fine detail; kraft gives a matte, tactile finish; specialty stocks are chosen for the touch.
Step 4: Match the finishing
Choose the finish last, once the material is fixed, because the substrate decides what will register cleanly.
- Foil stamping — metallic or coloured detail; needs a coated or laminated surface.
- Spot UV — gloss raised on a matte background; strong on soft-touch lamination.
- Embossing — tactile relief; best on uncoated or textured stock.
- Lamination — matte, gloss or soft-touch; also protects the print.
We hold registered foil, embossing and spot UV to the same artwork and the same ΔE ≤ 2 colour tolerance as the print.
The measurements that matter
| Specification | Target |
|---|---|
| Colour tolerance | ΔE ≤ 2 |
| Dimensional tolerance | ±0.5 mm |
| Board weight tolerance | ±5% of GSM (ISO 536) |
| Sample lead time | 3–8 days |
| Production lead time | 7–15 working days |
| Minimum order | 500 pcs |
Common mistakes
- Choosing finishing before structure — a finish that suits a rigid box rarely suits a folding carton.
- Going thicker than needed — extra GSM adds cost and can crack folds.
- Ignoring the crease — heavy board needs a deeper creasing matrix, not more glue.
- No written tolerance — without a stated ΔE and ±5% GSM figure, “close enough” is the default.
Conclusion
Work top to bottom: structure, then GSM, then face material, then finishing. Fix the tolerances in writing before production, and request a physical sample so you can judge stiffness and surface in the hand. See the rigid gift boxes we manufacture and our packaging materials library, or compare structures in grey board vs. corrugated. Zhengyang Packaging builds rigid gift boxes this way in Chang’an Town, Dongguan, and has produced color boxes, gift boxes and hang tags since 2006.
