Koroplast is a durable, waterproof, corrugated plastic material for signage that resembles “plastic card” in appearance. The hollow corrugated design makes this sign material extremely light, easy to handle and easy to use.
Due to its lightweight characteristics, Koroplast has become a popular alternative to rigid signs made of acrylic and PVC plastic. Signs made of corrugated plastic are also usually preferable to poster boards and foam core mounting plates. The foam core is not waterproof, and the surface is much more sensitive to damage than corrugated plastic.
Advantages of signs made of Coroplast
They have a slightly ribbed surface that looks like “plastic card”.
They are ideal for short-term outdoor use (good for 1-day event signs and serving up to 2 years).
They will last for decades indoors.
They are completely waterproof.
The standard thickness of 3/16″ (4 mm) is similar to that of hard cardboard.
Coroplast is easily available in high stiffness, 1/2″ thick.
They are highly resistant to extreme temperatures in cold and hot weather.
Signals made of Koroplast plastic can be one-sided or bidirectional.
They can be easily displayed and assembled.
Koroplast is a popular alternative to the foam core mounting plate.
How long does Coroplast last?
Corrugated plastic plates are not as flexible as vinyl flag and banner material, and not as rigid as solid plastic signs. Although custom-made corrugated plastic plates are usually used outdoors, strong winds can damage the corrugated plate material. Corrugated plastic plates are designed for both indoor and outdoor short-term plates. Coroplast signs used outdoors last for up to 2 years, while coroplast signs used indoors can last for +30 years.
