How Corrugated Board and Boxes Are Made

Learn how corrugated board and containers are made in this video from Georgia-Pacific Corrugated, which lays out the process from raw materials to finished boxes.

The series of equipment that creates corrugated board is called a corrugator. The first step in the process occurs in a machine called a single phaser, which combines a liner and a medium to form a single-face web.

When complete, the single-face web leaves the single phaser and is carried to the double glue unit, which applies cornstarch-based adhesive to the flute tips. After the adhesive is heat-cured, the combined board is scored, slit, and cut to specifications.

Afterwards, Georgia-Pacific’s converting machines, including rotary die cutters and flexo folder gluers, turn the corrugated sheets into finished, printed corrugated boxes.
