Industry Overview
Guangdong is one of China's largest greyboard paper production hubs, with its output closely tied to the province's thriving packaging and printing sectors. In 2024, Guangdong's total paper and board production reached a record 26.48 million tons, with packaging paper (including greyboard) accounting for a significant share. While specific greyboard output data remains proprietary, industry estimates suggest Guangdong contributes over 20% of China's greyboard supply, driven by demand from electronics, cosmetics, food, and e-commerce industries.
Product Classification:
Greyboard paper is categorized into single grey, double grey, and full grey based on coating layers and fiber composition. Double greyboard, with its balanced strength and cost-effectiveness, dominates Guangdong's production, while full greyboard (high-density) caters to premium packaging needs (e.g., luxury gift boxes, furniture packaging). Common grammages range from 250–3,500 g/m², with thicknesses spanning 0.35–4.48 mm to meet diverse application requirements.
Applications:
Packaging: Boxes for electronics, cosmetics, pharmaceuticals, and food.
Industrial: Partition boards, furniture liners, and automotive components.
Decoration: Picture frames, book covers, and architectural panels.
Sustainability: Increasingly used as a recyclable alternative to plastic and foam materials.
2. Industrial Supply Chain Analysis
2.1 Raw Material Sourcing
Greyboard production relies heavily on recycled (wastepaper), which constitutes 70–80% of inputs. Guangdong's well-developed wastepaper recycling network, supported by enterprises like Nine Dragons Paper (Dongguan), ensures stable raw material supply. For instance, Nine Dragons' wastepaper purchasing prices in 2024 ranged from 1,440–2,010 RMB/ton, reflecting market demand dynamics. Additionally, imported wood pulp and virgin fibers are used for high-end products, leveraging Guangdong's port advantages for cost-effective imports.
2.2 Production Technology & Equipment
Guangdong enterprises adopt advanced manufacturing technologies to enhance efficiency and quality:
Automation: Companies like Senyi Paper (Guangning) have upgraded production lines with intelligent control systems, achieving 800 kg greyboard output every 5 minutes and a 98% product yield.
Energy Efficiency: Wastewater recycling systems (e.g., EAS anaerobic systems) and biomass energy utilization reduce environmental impact. For example, Senyi Paper's (technical upgrades) cut energy consumption by 20% and achieved 85% wastewater reuse.
Product Innovation: Specialized products like thermoformed greyboard and eco-friendly bio-based coatings are gaining traction.
2.3 Downstream Demand Drivers
Guangdong's greyboard market is fueled by:
Manufacturing Clusters: The Pearl River Delta's electronics, textile, and consumer goods industries drive demand for packaging solutions.
E-commerce Growth: Online retail platforms require durable, lightweight packaging, boosting greyboard usage in shipping boxes and inserts.
Export-Oriented Economy: High-quality greyboard products from Guangdong are exported to Southeast Asia, Europe, and North America, capitalizing on the province's logistics networks.
