The Corrugator: The Heart of the Corrugated Board Production Line
Hold large rolls of paper (linerboard and medium) and feed them into the machine at controlled tension.
Use steam to soften the paper, making it pliable for forming strong, uniform flutes.
The defining component. Heated, gear-like rolls with precisely engraved flutes shape the medium paper into its characteristic wave pattern (A, B, C, E, or F flute profiles).
Paper rolls are mounted and fed into the line.
The medium passes through heated corrugating rolls to form its fluted shape.
Glue is applied to the flute tips, and a liner is pressed onto them to create single-face board.
The single-face board moves to the double facer to meet the second liner. For double or triple-wall board, the process repeats.
The board is heated to cure the adhesive bonds.
The continuous board is slit, scored, and cut into sheets ready for conversion (printing, die-cutting, etc.).
It produces board in a continuous, high-speed process, essential for meeting large-scale packaging demands.
Integrated systems ensure consistent flute formation, bond strength, and dimensional accuracy.
Can produce various board grades (single-, double-, triple-wall) and flute profiles by adjusting rolls and layers.
Modern corrugators are engineered to minimize waste, optimize adhesive use, and reduce energy consumption.
Modern Advancements
Today's corrugators feature advanced automation, IoT sensors, and data analytics for predictive maintenance and real-time monitoring. These innovations reduce downtime, improve product consistency, and lower operational costs. Energy-efficient designs and the ability to use recycled paper effectively also support greener production.
