Coroplast® is a type of corrugated plastic, generated by fusing two layers of corrugated plastic. One layer is in a wave pattern and the other layer is flat. The two layers are adhered together forming a stronger sheet of plastic.

Coroplast signs are widely used in indoor marketing. As these are light in weight and appreciated for cost effective visual marketing. Signs made with coroplast material are more tougher and solid than corrugated fiberboard and lighter than solid extruded plastic.

Corrugated plastic goes by a number of names including corriboard, Polyflute, FlutePlast, Proplex, Correx, Twinplast, Corriflute, Corflute, etc. Above all, Coroplast is the most common brand name for corrugated plastic sheets.

It is made from polypropylene, which is a non-biodegradable material. It’s still recyclable. Polypropylene is an extremely sturdy thermoplastic polymer with a neutral pH that allows it to withstand all kinds of external temperature, weather, and usage conditions for long periods of time with minimal wear and tear.
