How is Corrugated Made?

Corrugated board, which is sometimes called Cardboard, is a widely used material in the packaging industry due to its robustness, durability, and versatility. It is used to make boxes, cartons, and other packaging materials. Corrugated board is made by sandwiching a fluted or wavy material between two flat liner boards. The fluted material provides cushioning and protects the contents of the package during shipping and handling.

Let’s take a closer look at how corrugated board is made.

1

Making the liner board

The first step in making corrugated board is to create the liner board. The liner board is a flat sheet of paper that will be glued to the fluted material to create the final product. The liner board is made by feeding a roll of paper through a series of rollers, which smooths and compresses the paper to the desired thickness.

Creating the fluted material

The fluted material is the wavy layer of corrugated board that provides cushioning and strength to the packaging material. This layer is created by feeding a roll of paper through a machine called a corrugator. The corrugator has a series of heated rollers and plates that shape the paper into a series of wavy or fluted layers.

Gluing the layers together

Once the liner board and fluted material have been created, they are glued together to create the final product. The liner board is placed on either side of the fluted material and then fed through a machine that applies a special adhesive to the edges of the liner board. The liner board is then pressed onto the fluted material, and the adhesive is allowed to dry and cure.

Cutting and shaping the corrugated board

The final step in creating corrugated board is to cut and shape it into the desired shape and size. This is done using a machine called a slitter-scorer, which cuts the board into the desired length and shape. The finished corrugated board is then stacked, bundled, and shipped to the packaging manufacturer or customer.

To Summarize:

Corrugated board, which is sometimes called Cardboard, is a widely used material in the packaging industry due to its robustness, durability, and versatility. It is used to make boxes, cartons, and other packaging materials. Corrugated board is made by sandwiching a fluted or wavy material between two flat liner boards.
