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. Corrugated plastic is a type of plastic cardboard that consists of three layers of polypropylene plastic substrate.
The two external layers, which are known as twin-wall plastic sheeting due to their uniform design and parallel positions, hold together an internal layer of honeycomb-shaped plastic. This makes corrugated plastic sheets one of the most lightweight, versatile, and shock-absorbent plastic materials on the market. 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.
