No, "
Coroplast" is a brand name. The sheet you are talking about is not corrugated, but is instead extruded cells. Corrugations are undulating waves/patterns in a single-thickness material, which is often bonded to other materials (i.e. cardboard). It's not the cells that make the cardboard or plastic corrugated, but the manner of making the cells.
