We work with several different types of plastic signs here at Signature Sign Studios. The 3 main types are Coroplast, PVC, and Sintra.


Corrugated plastic sheets, more commonly known as “Coroplast,” are a lightweight and cheap sign material, perfect for temporary outdoor signs or interior signs. You might also consider it as “fancy cardboard”. If you’d use cardboard for a job, then Coroplast is a more durable and professional upgrade.

They come in a wide-variety of colors and are applied with vinyl lettering and digital print graphics.

We don’t recommend Coroplast for long-term outdoor usage as it generally has a life of only one to two years. However, Plywood or metal-plastic composites are great, more durable alternatives. It looks like this:

Benefits Of Coroplast:

Some of the big benefits of Coroplast are:

  • Made very quickly (no waiting for paint to dry as all artwork and text is done with vinyl)
  • Very light (try moving a plywood sign, it can be quite difficult!)
  • Lowest cost signs available
  • Very easy to install (sometimes you can even install them with just a zap strap!)
  • If you have an existing sign that needs to be updated (ie. 10 houses left!), it’s a great temporary holder to update information on your signs.

If you need quick, temporary signage, Coroplast can be a great option.

Downsides Of Coroplast:

As great as it is, Coroplast isn’t the perfect material for every job. A few downsides are:

  • It doesn’t last as long as other signs
  • They can warp in the heat
  • In the winter, because there are holes throughout the Coroplast, water can get into it, freeze, and crack it.
  • They aren’t as beautiful as other types of signs; they’re a little homely looking when you get up close.

How Long Does Coroplast Last?

There are 2 main types of Coroplast.

3mm Coroplast (basic type)

  • cheaper than 10mm Coroplast
  • shorter longevity
  • commonly used for: sale promotions, direction signs, real estate signs, for sale signs, lawn signs, trade shows, conference signs, exhibit and display signs
3mm Coroplast
1 Year Average Longevity


10mm Coroplast (large type)

  • a very thick plastic
  • higher longevity
  • commonly used for: real estate developers, small home businesses, trade shows, sale promotions
10mm Coroplast
2 Year Average Longevity



As you can see, the longevity of a thicker Coroplast (10mm) is considerably higher than the 3mm, but it comes along with a higher cost. 3mm Coroplast is our most common seller for plastic signs.

PVC Plastic Signs

The main brand of PVC that we use for our signs is called Komacel. It’s flat, rather than bumpy (like Coroplast).commonly used for: 3D cutout letters, plywood sign replacement, primary signs for small businesses, warning signs, property signs

Benefits Of PVC Komacel:

  • Very flat (no bumps)
  • Looks better than Coroplast
  • Very lightweight
  • Doesn’t rot
  • Doesn’t expand & contract
  • Doesn’t crack (like Coroplast does).

Komacel is a great option for much longer term signs. If you want a plastic sign that lasts a long time, this is your main choice.

Downsides Of PVC Komacel:

  • More expensive than other types of plastic.
