• Wood Selection: Trees, often softwoods like pine or spruce, are harvested from managed forests. The choice of wood species impacts the final product’s strength and suitability for different applications.
• Debarking and Chipping: The logs are debarked to remove the outer layer and then chipped into small pieces. This process prepares the wood for pulping.
• Pulping: The wood chips are then converted into pulp through either mechanical or chemical pulping methods. Mechanical pulping uses grinding to separate the fibers, yielding a higher yield but a weaker pulp. Chemical pulping, using chemicals like sulfite or sulfate, dissolves the lignin that binds the wood fibers together, producing a stronger pulp. The specific method used depends on the desired characteristics of the final cardboard.

Paperboard Formation

The pulped wood fibers are then transformed into paperboard, the foundational material for cardboard food containers.

• Pulp Preparation: The pulp is mixed with water to create a slurry. This slurry may also include additives such as sizing agents for water resistance, dyes for color, and strengthening agents to enhance the paperboard’s structural integrity.
• Sheet Formation: The slurry is spread onto a moving wire mesh, allowing the water to drain and the fibers to interlock, forming a continuous sheet. This sheet then passes through a series of rollers that press and dry the paperboard.
• Multi-Ply Construction (for Corrugated Cardboard): For corrugated cardboard, multiple layers of paperboard are combined. A corrugated medium, created by passing paperboard through fluted rollers, is glued between two flat linerboards to create the characteristic structure. The flute profile (A, B, C, E, F) affects the cardboard’s strength and cushioning properties.

Coating and Treatment

To ensure food safety, moisture resistance, and grease resistance, the paperboard undergoes various coating and treatment processes. These processes are essential to prevent the cardboard from degrading when it comes into contact with food and liquids.
