Industrial grey cardboard (also known as grey board paper, grey bottom white board paper or industrial cardboard) is a high-density, high-strength cardboard widely used in packaging, printing, furniture, construction templates and other fields. Its Industrial cardboard production line has significant advantages in production efficiency, product quality, cost control, and environmental performance. The following are the main production advantages of the industrial hard paperboard production line :

1. High efficiency and large-scale production

Continuous production: Using assembly line operations, the entire process from slurry preparation, forming, pressing, drying to slitting and stacking is automated, greatly increasing production capacity (up to hundreds of tons per day).

Low downtime: The automation control system monitors equipment status in real-time to reduce downtime caused by malfunctions.

2. Stable and reliable product quality

Uniformity control: Through advanced flow box and forming technology, ensure consistency in cardboard thickness and weight (within ± 1%).

High strength performance: Multi layer composite technology (such as long mesh multi cylinder technology) enhances compression resistance, tear resistance, and folding resistance, making it suitable for heavy-duty packaging.

Surface flatness: Precision calendering technology makes the surface of the cardboard smooth, which is conducive to subsequent printing or laminating.

3. Strong adaptability of raw materials

High utilization rate of waste paper: Recycled waste paper (OCC, mixed waste paper) can be used as the main raw material to reduce fiber costs.

Flexible pulp ratio: supports the mixing of various fibers such as wood pulp, bamboo pulp, and straw pulp to meet different strength requirements.

4. Energy saving and environmental protection advantages

Wastewater circulation system: Closed white water reuse technology reduces water consumption (with a water-saving rate of over 80%).

Waste heat recovery: The waste heat from the drying process is used to preheat the air or slurry, reducing energy consumption.

Low emissions: equipped with alkali recovery or biological treatment facilities to achieve standard discharge of wastewater and exhaust gas

Renewable materials: 100% biodegradable, in line with global plastic ban and restriction policies.

5. Cost control advantages

Large scale cost reduction: The production cost per ton significantly decreases with the expansion of production capacity (electricity consumption and labor sharing decrease).

Waste recycling: scraps and damaged paper can be directly recycled, with a material utilization rate of over 95%.
Labor savings: Automated production lines only require a small number of personnel for monitoring, reducing labor costs by more than 50%.

6. Widely used downstream applications

Packaging field: high-end gift boxes, electronic product liners, logistics pallets.

Printing industry: book covers, hang tags, handbags.

Industrial use: Furniture backboards, temporary building templates, automotive interior substrates.
7. Potential for technological upgrading

Intelligent transformation: Integrating IoT and AI systems to achieve predictive maintenance and process optimization.

Green technology iteration: such as biological enzyme de ink, solar drying, etc. to further reduce carbon footprint.
summarize

The industrial grey paper cardboard production line has become an ideal alternative to traditional materials such as plastics and wooden boards through its core advantages of high efficiency, low cost, and environmental compliance. In the future, with the promotion of low-carbon economy, the value of this production line in the circular economy will be further highlighted.
