Campaign Yard Sign Substrate – Corrugated Plastic

Corrugated plastic is created by bonding two flat polymer sheets with plastic flutes in between. It looks like corrugated cardboard and comes in a variety of colors. The tubes make the material rigid but also lightweight. Corrugated plastic is often referred to by brand names particularly Coroplast but also IntePro, Correx, Twinplast, Corriflute, or Corflute. It is also known as corriboard or twinfall plastic.

The most important qualities of the substrate as campaign lawn signs include rigidity, easily cleanable, and print quality characteristics that allow for anything a simple single color to a digital image. While the rigidity maintains the shape of the yard sign much better than a poly bag sign, it also makes the lawn sign more susceptible to the wind. These lawn signs can blow away in the wind in the most extreme cases. The rigidity of these yard signs allows campaigns to use them to other purposes such as rally signs or for visibility.

The smooth plastic surface and the rigidity lend themselves to easy cleaning. If a yard sign has been on a lawn for a long time, the sign will accumulate dust and dirt. Corrugated plastic signs can be wiped clean with a wet towel. This sign substrate will also withstand chemical cleaners if needed.

Some candidates have shaped their coroplast signs like their state or district while others have used shapes that help identify who they are what they are running for such as a sheriff’s badge or an apple indicating the candidate was a teacher.

Printing on corrugated plastic has its challenges. Coroplast is sensitive to the type of ink and its application to cure properly. It is important to use a printer that has experienced with corrugated plastic because applying too much ink or ink that is too thick will not adhere properly to the yard sign.
