How to Make Corrugated Cardboard

If you have ever been interested in making your own paper, but found that was a little too tame for you, then you might be interested in making a hardier substance. Corrugated cardboard, which is used for boxes and often employed by children for fort construction, is a handy thing to have around and a great craft material. For a designer product or a science project, here is how to make your own corrugated cardboard.

Difficulty: Easy

Instructions

Things You'll Need:

• 2 sheets of 2-foot by 2-foot chipboard
• A package of construction paper
• Spray adhesive

1. Lay down one sheet of chip board on a flat surface.

2. Take a sheet of construction paper and begin folding it into 1/2 inch folds. This doesn't have to be exact because you will be folding many of these. After you fold them into ½ inch folds, it will look like an accordion. Fold as many pieces of construction paper as needed to layer the entire piece of chip board.

3. Spray a coating of spray adhesive directly onto the chipboard. You can spray liberally.

4. Lay down your folded construction paper until it fills the chipboard end to end and side by side. You will see the corrugation start to manifest itself.

5. Spray another coating of adhesive directly on top of the exposed accordion-folded construction paper. As before, you can be quite liberal with the adhesive since it has a lot to hold together.

6. Lay your other piece of chip board directly onto the pieces of folded construction paper. You can press it down lightly, but not too hard or you will flatten the construction paper.

7. Allow your homemade corrugated cardboard to dry overnight. You will have a solid piece of corrugated cardboard. You can make as many if these as you would like.

Tips & Warnings

• Use your corrugated cardboard to build sturdy fortresses or assemble a homemade science project display.
