Campaign Sign Substrate – Corrugated Plastic
Corrugated plastic is created by joining two flat sheets of polymer with plastic channels in between. It looks like corrugated cardboard and comes in a variety of colors. The tubes make the material stiff but also light. Corrugated plastic is often referred to by brand names, notably Coroplast, but also IntePro, Correx, Twinplast, Corriflute or Corflute. It is also known as corriboard or plastic twinfall.
The most important qualities of the substrate as campaign lawn signs include stiffness, ease of cleaning and print quality characteristics that allow for anything from a simple single color to a digital image. While the stiffness keeps the yard sign in shape much better than a poly bag sign, it also makes the lawn sign more susceptible to 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 for other purposes such as visibility or rally signs.
The smooth plastic surface and rigidity lends itself to easy cleaning. If a yard sign has been on the lawn for a long time, the sign will collect dust and dirt. Corrugated plastic signs can be cleaned with a damp towel. This sign substrate will also resist chemical cleaners if needed.
The biggest benefit of choosing this substrate is the ability to shape it however the campaign wants their sign to look. With a folding tag or poly bag tag, you are limited to a standard rectangular shape, but with corrugated plastic there are a variety of options. 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 experience with corrugated plastic because applying too much ink or ink that is too thick will not adhere properly to the yard sign.
Other popular lawn sign substrates include polythene bags and polythene-coated cardboard, also called folding signs. Take some time to consider the three types of lawn signs before deciding which one is best for your campaign. Coroplast is often a great choice for a lawn campaign sign.
