What is Coroplast?

A great use of Coroplast, Taste the Rainbow

If you’ve been exploring ChurchStageDesignIdeas.com for a while, you’ll see many designs use a material called Coroplast. But what is Coroplast, exactly?

Coroplast is a brand name for corrugated plastic. Just like Kleenex is a type of facial tissue, Coroplast is a type of corrugated plastic.

What is corrugated plastic?

Coroplast, or Corrugated Plastic

Corrugated plastic is simply the plastic equivalent of cardboard. It’s two sheets of plastic separated by another layer of zigzagged plastic. Coroplast, or corrugated plastic, is the same material real estate agents use for their yard signs. Sign companies/printers frequently used it for large signs. (You’ve seen the stuff around.)

What makes Coroplast so good for stage design?

Coroplast is lightweight, inexpensive, and fairly sturdy. Plus, it comes in various colors ā€“ including a translucent color that catches light wonderfully. Natural Coroplast, or clear corrugated plastic, is commonly used in stage design because the corrugation catches and reflects the light making the sheet seem to glow. You can back-light Natural Coroplast, whereas other colors need to be front-lit.

Where can I get Coroplast?

You’ll find Coroplast at sign stores, home improvement stores, and plastics manufacturers. You can check Coroplast.com‘s site for distributors of the name brand stuff. It usually comes in 4’x8’ sheets for anywhere between $10-20. It should be pretty easy to find sheets for $14.

Great stage designs that use Coroplast.

  • The Weave – Coroplast curved into a woven-looking structure.
  • Taste the Rainbow – A simpler version of the weave, with the corrugated plastic left unbent.
  • Radiant Squares – Square boxes that couple nicely with LED lights.
  • Squared Wings – Coroplast cut into different shapes that look like large mobiles.
  • Light Pillars – Corrugated plastic and tape form columns of light.
  • Destroyed Angel Wings – Small strips of Coroplast arranged to create a great textured backdrop.
  • 3D Coroplast – Using different colors of corrugated plastic for different looks.

So what will you make with this inexpensive and versatile material?

  1. I’ve been searching all over for an efficient way to get my hands on large sheets of coroplast without insane shipping costs. I just found that Home Depot sells them in bundles on their website that get direct shipped to your local store for pickup. Here’s a link if anyone is looking for an inexpensive way to get this for their stage designs.


    • Is “White” and the “Natural” or “Clear” the same thing? I saw the Home Depot Bundle but didn’t know if this is what is shown in the pics or not.

        White is a solid white color. Natural is translucent. Clear is much more translucent…almost clear even.

        Most churches use Natural if they want to back light it. If you want to front light it only, use White.

        • Has anyone found a way to get the natural color coroplast at a decent shipping price? We are really wanting to do some backlighting and so far we are having to use fabrics which just aren’t that great, would love to get some natural if thats what is best for back lighting.

    What is Coroplast made of? Is it a petroleum product? Or is it made from recycled plastic? Or is it plastic made from cellulose?

  3. Anywhere to get the Natural where I don’t have to order such a huge amount? The Coroplast site looks like you have to order an entire pallet which is like 275 sheets.

      There are two suppliers in Michigan that would order but 100 sheets in a pallet…If there were enough Midwest fold who could use, maybe we could go together and order? I’d take 20 sheets…

  4. We have coroplast in 6″x18″ pieces that we cut off of a sheet. I have my employees keeping these pieces but need an idea of what to do with them. They are a scrap piece for us but I can’t imagine throwing them away. I have sold some to people for .10 each but I have thousands and will take forever to sell them in 10 -20 pieces at a time. Any ideas on what to do with these small pieces ?

  5. Coroplast sheets are an excellent option for any sort of display application, mostly because it is extremely resistant to weather conditions or chemical exposure. Coroplast sheets are the go-to option for outdoor applications and screen printing because of those properties.

  6. Is coroplast safe to us for led lights?…we want to do a church stage design but for the time we already dound coroplast but still aren’t sure if it safe against fire…..

  7. Thank u sooo much……..

  8. is there a good place to get grey coroplast without the high shipping costs?

    Here’s a couple helpful tips for those of you looking to purchase the Natural Coroplast:
    1. You can’t buy it at home depot and most sign stores won’t carry that color.
    2. Start with going here: http://www.coroplast.com/distributor/ to check your states authorized distributors. Call them and tell them how many sheets you want and make sure to specify you want the natural color. A lot of times these companies either won’t have the color you want or won’t ship/sell to you unless you’re a business account or purchase a whole pallet (think like 250 sheets) of it. But this is still the best way to go.
    3. If you can’t find any in your state that work check a neighboring state, typically one with a major city in it. Do the same thing as in step 2.
    4. If all else fails looks up San Diego Plastics. They will ship all over the country I believe. They usually will want to cut up the sheets to make them easier to ship but you might be able to get them to ship as whole sheets if you’re desperate and don’t mind paying extra for shipping.

  12. Which coroplast is more efficient, is it the the 2mm, 3mm or 4mm?

  13. What’s the best tool for cutting it?

  14. I am a salesman from the corrugated plastic sheet factory in China. If you need a large number of corrugated plastic sheet, please contact me, and also welcome distributors from all over the world to cooperate with us.

  15. We didn’t have a Coroplast distributor within a 2 hour drive of us, but we’ve developed a great relationship with N. Glantz & Son’s nearest depot. They have weekly deliveries to our town… we pay just a couple of dollars shipping no matter if we order 1 sheet or 30 sheets.
