Coroplast Sheet is a lightweight fluted sheet. It outperforms corrugated fibreboard in most printing applications. The strength of this material is dependent on the flute direction. The second dimension specifies the flute direction.


Coroplast Sheet is a profile sheet with 2 skins separated by vertical ribs. These ribs create a series of “flutes” that run the length of the sheet. The square box shape of the flutes makes the sheets rigid and strong. The skins and ribs are very thin making the sheets very lightweight, especially compared to solid sheets. This lightweight strength combines with excellent weather resistance, chemical resistance and durability to create products that can satisfy many needs in packaging, signs and glazing applications.
