The corrugating units form flute profiles on the medium paper.
- Gluing
Adhesive is applied to bond liner paper and corrugated medium.
- Laminating
Multiple layers are bonded together to form 3-ply, 5-ply, or 7-ply corrugated board.
- Heating and Drying
The board passes through heating sections to complete bonding and moisture control.
- Slitting and Scoring
The board is slit and scored according to required carton sizes.

Frequently Asked Questions
What Is a Corrugated Cardboard Production Line?
A corrugated cardboard production line is a complete manufacturing system that converts paper rolls into corrugated sheets through processes including corrugating, gluing, laminating, heating, cutting, and stacking.
How Is Corrugated Board Made?
Corrugated board is made by combining liner paper and corrugating medium through a series of production processes. The medium paper is first shaped into flutes by corrugating rolls, then glued with liner paper to form single-face board. Multiple layers are bonded together through heating and laminating to produce 3-ply, 5-ply, or 7-ply corrugated board. The finished board is then slit, cut, and stacked for further carton converting processes.
What Is the Difference Between 3-Ply, 5-Ply, and 7-Ply Corrugated Board?
3-ply produces single-wall corrugated board for general packaging.
5-ply produces double-wall corrugated board with higher strength for heavier packaging requirements.
7-ply produces triple-wall corrugated board designed for heavy-duty industrial and export packaging.
What Working Widths Are Available?
Standard working widths range from 1400 mm to 3300 mm. Customized working widths are also available according to production requirements.
Which Flute Profiles Can the Production Line Produce?
The production line supports common flute profiles including A, B, C, E, F, G, and N flute. The available flute combinations depend on the selected production line configuration and corrugating rolls.
Can the Production Line Be Customized?
Yes. The production line can be customized according to board structure, working width, production speed, flute requirements, automation level, production capacity, and factory layout.
What Factors Should Be Considered When Selecting a Corrugated Board Production Line?
The selection depends on required board structure, production capacity, working width, flute combination, factory space, automation requirements, and target packaging applications.
