Corrugated cardboard is the thick brown material that makes up all cardboard boxes. The process for making corrugated cardboard is fairly complex and involves several very large machines. However if you only need a few small sheets of cardboard and don't have any handy, you can make a cardboard substitute out of just a few pieces of paper!

  1. You'll need five sheets of paper and some glue. A glue stick or some craft glue will work the best.
    • The dimensions of your paper will affect the size of your cardboard, so use smaller paper if you want a smaller piece of cardboard.
    • Using more sheets of paper will result in thicker cardboard.
    • If using liquid glue, consider spreading out some newspaper to catch any glue that drips off of your cardboard.
  2. Spread your glue on one side of a sheet of paper, then align a second sheet of paper and stick them together. The corners and edges should align as closely as possible. This will form the foundation for your cardboard.

  3. Run the heel of your hand across the foundation, both from the bottom of the page to the top and from side to side. Make sure all sides and corners are glued together.
    • If any edges or corners are loose, pull them apart as little as possible and add more glue. Reattach the sheets and press together again.
  4. Spread glue on the top page of your foundation, then align and attach another sheet of paper. Make sure to line up the corners and edges before sticking the pages together. Firmly press down on the foundation after each sheet of paper is added to make sure all of the paper is staying glued together. Continue to add sheets onto the foundation until your cardboard is the desired thickness.
    • Adding more sheets of paper will increase the thickness of your cardboard.
  5. Put your cardboard under a fan or in a warm location to speed up the drying process.
    • Be patient! If the glue doesn't dry completely your cardboard may fall apart.

Making Corrugated Cardboard

  1. Cardboard is simply a sheet of ridged paper sandwiched in between two sheets of flat paper. The corrugator organizes and assembles the three different sheets to make corrugated cardboard. [1]
    • The ridged paper increases the stability and durability of the cardboard while using a relatively small amount of paper.
  2. The machine heats the flat paper to 350 degrees Fahrenheit and pushes it through ridged rollers. The result is a sheet of paper with a repeating U-shaped design that will be used as the core of the cardboard. [2]
  3. The corrugator applies a starch-based glue to one side of the ridged sheet, which is then pressed onto a sheet of flat paper. The same process is used to apply another flat sheet to the untouched side of the ridged sheet, creating the familiar corrugated sheet of cardboard. [3]
  4. Further cuts and perforations are made to allow for folding into various shaped boxes and containers. [4]

  • Question
    Will it be very stiff like cardboard?
    Community Answer
    If you use many pieces of paper, yes. The more pieces there are, the thicker it gets, resulting in harder paper.

  • Question
    How do I cut and bend the cardboard into a box?
    Community Answer
    Always start with a large piece of cardboard. In the middle, you'll have the layout of one square in the middle and four squares on each side of your first square (forming a plus sign). Choose one of the sides and then add an additional square, which will serve as the lid. In the end your box should look like a cross. (Make the measurements exact so the box comes together properly.) Then, I would recommend scoring each line before folding the box.

  • Question
    Is the cardboard sturdy enough to make a shelf or will it break?
    Community Answer
    It depends upon what you want to put on the shelf, and the thickness of you cardboard. You can't put any liquids that might spill on it either, that would ruin the cardboard.

      • The more sheets you add, the thicker the cardboard will be. Make sure the glue is fully dried or else it could fall apart. You may also want to consider card stock or other thick paper. Construction paper may work too.
      • if you use cardstock, you might not have to apply that many layers of card stock.
      • Be sure to put glue all over one side of the paper, not just around the edges.
