Greyboard Thickness for Rigid Boxes: 800 vs 1200 vs 1800gsm
We have been making packaging for over fifteen years, and the question we hear most often is: "How thick should the greyboard be? Is 800gsm enough?"
Short answer: For most cosmetic sets and tea gift boxes holding 200–600g of product, 1200gsm is the sweet spot. Use 800gsm for light contents such as lipstick or single sheet masks, and 1500–1800gsm only for heavy gift boxes such as wine or electronics. For EU shipments, stay at 800–1200gsm.
Many buyers assume "thicker means more premium". That is only half true. Below is our own test data, so you can spend money where it actually shows.
1. What "gsm" means on greyboard
When greyboard is labelled 800g, 1200g or 1800g, that number is the weight per square metre — not the thickness. In practice weight and thickness rise together, so most buyers use them interchangeably:
| Greyboard | Thickness | Character |
|---|---|---|
| 800gsm | approx. 1.2 mm | Light, flexible, cheapest |
| 1200gsm | approx. 1.8 mm | Medium rigidity |
| 1800gsm | approx. 2.63 mm | Hard, heavy, most expensive |
On the same box size, an 1800gsm board weighs more than twice as much as 800gsm — and freight rises with it. So "thicker is better" is only half the story.
2. Our test: same box, same product, three thicknesses
We built the same 20 × 20 × 6 cm rigid telescope box in all three grades, loaded each with the same 380 g glass bottle, and compared them:
| Greyboard | Empty box weight | Press test | Drop test |
|---|---|---|---|
| 800gsm | 85 g | Top dents slightly under pressure, but holds shape once filled | 1.2 m onto wooden floor — light crease on corners |
| 1200gsm | 128 g | No visible give under pressure | 1.2 m — intact. Noticeably "solid" in the hand |
| 1800gsm | 185 g | Rigidity beyond what the product needs | 1.5 m — no damage, but freight adds about CNY 0.80 per box |
Conclusion: for contents between 300 and 500 g — cosmetic sets, tea gift boxes — 1200gsm is the value sweet spot. 800gsm suits light products such as lipstick or single sheet masks. 1800gsm belongs on heavy gift boxes such as wine or electronic devices.
3. The wrapping paper changes perceived quality more than the board does
Plenty of buyers touch an 1800gsm box and call it premium — but much of that impression actually comes from the wrapping paper. On the same 1200gsm board:
128gsm gloss art paper — feels smooth but thin, like a hardcover book.
120gsm soft-touch matte paper — feels velvety. Perceived quality jumps, and most people assume the board is 1800gsm.
Textured specialty paper (cotton, laid, kraft-look) — strong tactile grain, suited to a crafted or understated premium look.
The smart way to save: 1200gsm board + soft-touch paper costs about 15% less than 1800gsm board + gloss art paper — and it feels better in the hand.
4. PPWR: thicker greyboard is harder to recycle
If you export in 2026, this matters. Greyboard is made from recycled pulp and is recyclable in principle — but:
• Thicker board needs more adhesive to wrap, and the layers separate less easily during de-inking.
• European sorting lines sometimes classify 1800gsm boxes as heavy reject, which downgrades the recycling stream.
• 800–1200gsm + aqueous coating + a glue-free magnetic structure is the combination PPWR treats most favourably.
For EU-bound boxes, do not specify 1800gsm by default. The compliance risk is worth more than the gain in feel.
5. Quick reference
| Contents | Recommended greyboard |
|---|---|
| Under 200 g — lipstick, small accessories | 800gsm is enough |
| 200–600 g — cosmetic sets, tea cakes | 1200gsm (sweet spot) |
| Over 600 g — wine bottles, devices | 1500–1800gsm |
| Exporting to the EU | 800–1200gsm + aqueous coating + separable structure |
Not sure which thickness fits your product?
We are based in Bao'an, Shenzhen, with our own die-cutting room and aqueous coating line. MOQ is 500 pcs, and structural samples ship within 24 hours.
During sampling we build the same box in all three grades as white dummy samples, so you can compare feel, weight and cost side by side — and choose without paying for the wrong one.
Send us your product weight and box dimensions, and we will tell you what we would use, and why. If the honest answer is the cheaper option, we will say so.
