GC2 Folding Box Board
GC2 is a coated folding boxboard category with a cream reverse side. For folding cartons, compare the proposed factory grade's caliper, stiffness, print surface and creasing behaviour against your design. Our Chengdu team coordinates technical sheets, samples and quotations for buyers sourcing from China.

- Consumer-goods folding cartons
- Dry-product retail packaging where the cream reverse is acceptable
- Printed sleeves and covers subject to conversion approval
Technical specification & TDS verification
GC2 alone does not set a universal GSM, stiffness or quality level. Factory TDS values and tolerances are confirmed for the selected grade.
| Parameter | Buyer requirement / factory evidence | Test / verification method |
|---|---|---|
| Category and construction | GC2 cream reverse, furnish/construction statement and top-surface coating required. | Supplier declaration and approved sample. |
| Grammage | Target GSM and acceptance tolerance. | ISO 536 or the agreed method. |
| Thickness / bulk | Caliper and bulk target relative to carton geometry and handling. | ISO 534 or the agreed method. |
| Bending resistance | Machine/cross-direction targets, units, test geometry and tolerance. | ISO 2493-1 or the stated buyer-approved method. |
| Top surface and print | Printing technology, coating finish, brightness and surface targets; identify the optical method. | Supplier TDS with methods plus print trial. |
| Moisture / Cobb | Acceptance range and Cobb test duration where relevant. | ISO 287 and ISO 535 where applicable. |
| Conversion | Grain direction, crease quality, fold cracking, glueing and carton-line acceptance. | Buyer conversion trial with agreed settings. |
Testing & document requirements
Grade and performance comparison
Request the proposed grade's dated technical sheet and a representative sample showing the cream reverse. Compare grammage, caliper, bulk and bending resistance together, with methods, units, direction and tolerances recorded.
Carton conversion approval
Share the carton dimensions, grain direction, printing process and packed product weight. Agree trial criteria for cutting, creasing, folding, gluing and appearance before confirming the commercial specification.
Application and fibre claims
State any certified-fibre claim and documentation your order requires. Where the board will contact food directly, specify the contents, contact conditions and destination so the exact proposed grade can be assessed against the required documents and tests.
Packing & container planning
- Sheets or reels and dimensions
- Grain direction
- Core and maximum reel diameter
- Pallet stack height and weight
- Protective wrap and edge protection
- Grade/batch labels and actual shipment plan
| Planning field | Information to confirm |
|---|---|
| Shipment format | Reels, sheets or converted blanks; quantity by grade and net metric tonnes. |
| Reel handling | Width, maximum diameter, core inside diameter, maximum reel weight, winding direction and splice limits. |
| Sheet handling | Sheet dimensions, grain direction, sheets per stack, pallet dimensions, maximum stack height and pallet gross weight. |
| Protection and traceability | Moisture-resistant wrap, edge protection, end protection, pallet/packing specification, grade and batch labels. |
| Container plan | 20GP/40HQ option, actual package dimensions and gross weights, securing plan, equipment payload and destination handling/road limits; final net tonnes confirmed against the packing list. |
| Commercial basis | Named origin/destination, Incoterm, currency, quote validity, payment terms, required documents and target shipment window. |
Net cargo quantity is an order-specific result of dimensions, packing, actual weight and the relevant equipment and transport limits.

- Submit the application, specification and any reference TDS.
- Review the proposed factory grade and document scope.
- Approve a representative sample against the agreed acceptance criteria.
- Confirm the quotation, inspection scope, packing and shipment terms in writing.
Buying questions
What is the difference between GC1 and GC2?
GC1 has a white reverse and GC2 has a cream reverse. This category difference does not replace comparison of caliper, stiffness, print surface and conversion performance.
Can you quote a high-bulk GC2 grade?
Provide the desired GSM, thickness/bulk, stiffness method and carton use. We ask factories for a documented grade that meets the required combination rather than promising an unspecified high-bulk range.
Does GC2 mean food-grade board?
No. A grade code does not establish food-contact compliance. For direct food contact, state the market and intended use and request suitable grade-specific documents and tests.
What should I send with a quotation request?
Send company details, target GSM and tolerance, dimensions and grain direction, sample or current TDS, end use, quantity, destination and required timing.
