Import Black Cardboards — Buy in Bulk from Supplier in China

Ningbo Green Do Paper Co., Ltd. produces black cardboards from a blended furnish of wood pulp and recycled paper, offering a paperboard solution for packaging, display and craft applications. The standard sheet size is 31 inches by 43 inches, a format that suits flatbed die-cutting and sheet-fed printing operations. The board is engineered for rigidity and surface integrity, with a smooth face that accepts printing and finishing processes without excessive show-through or fibre lift. The black colour is achieved through mass-dyed fibres rather than surface coating alone, which gives more consistent edge colour and reduces the risk of white-line exposure after creasing or cutting.

Typical grammage for this product category ranges from 200 gsm to 400 gsm, though the supplier does not state a specific basis weight for this listing. Caliper, stiffness and internal bond strength are the critical performance parameters for carton conversion; buyers should request the TAPPI T411 caliper, the Taber stiffness index (TAPPI T489 or T566), and the Scott internal bond value (TAPPI T569) to ensure the board will run on their folding-gluing or rigid-box lines. The recycled content supports sustainability claims, but exact post-consumer percentage should be confirmed if certification to FSC Recycled or equivalent is required. pH and alkaline reserve data are relevant for archival or photographic packaging applications and should be requested if product longevity is a concern.

This material finds use in luxury rigid boxes, cosmetic folding cartons, photographic portfolio covers, point-of-sale displays and premium craft applications. Buyers are typically packaging converters, print finishers, stationery brands and specialty retailers. The supplier is located in Fenghua, Zhejiang Province, with access to Ningbo port for containerised export. No MOQ, price, lead time or certification status is stated in the source data; these must be confirmed directly with Ningbo Green Do Paper Co., Ltd. before placing an order. Payment terms, Incoterms and sample availability are also matters for direct negotiation.

Ningbo Green Do Paper Co., Ltd. is based at Shangqiao Sci-Tech Industrial Park, Fenghua, Zhejiang Province, China, with registered operations in the 315500 postal zone.

The supplier does not display verification badges, response metrics or transaction history in the provided data.

The listing presents the company as a source of black cardboards with a stated sheet size and material composition, but it does not disclose production capacity, number of employees, year of establishment, revenue figures, named clients, specific machinery lines, or environmental certifications such as FSC, PEFC or ISO 9001. Buyers should therefore conduct due diligence on factory capability, quality management systems and social compliance before committing to volume orders. The address places the supplier within the Ningbo economic region, which has established paper and packaging supply chains and port access.
