What is Coroplast in Large Format Printing?

Skip to Uses


Coroplast is a type of corrugated plastic, often used in sign materials. Corrugated materials feature a liner made of a folded material sandwiched between two flat layers. The inner layer’s ridges and furrows help to strengthen and reinforce the board. People often call coroplast “plastic cardboard” because of its design and appearance.

The word “coroplast” is a brand name of a product first developed in the 1970s. Although there are other brands of corrugated plastic available, the name coroplast is often used generically to refer to any corrugated plastic, similar to the way people ask for a Kleenex instead of a tissue.

Why choose coro signs over other types of material for your signage? Corrugated plastic holds up well against the weather – it won’t get soggy in the rain or melt in the heat. You can also recycle the material. Manufacturers often make coro out of polypropylene, or #5 plastic, which many communities recycle.

Along with being weather-resistant, coroplast is very durable. It won’t break down or tear easily, which is another reason they’re great for outdoor uses. Last but not least, we can print on both sides of this material. This means you can get double the exposure!
