Coroplast refers to a lightweight, durable, and versatile corrugated plastic sheet made from polypropylene copolymer resin. It is a popular material for a wide range of applications due to its affordability, weather resistance, and adaptability.

Coroplast is a brand name for corrugated plastic sheets, which are made from a high-quality, polypropylene copolymer. This material is lightweight, durable, and weather-resistant, making it ideal for a variety of uses. Coroplast sheets are composed of three layers: two flat outer layers (also called skins) and a ribbed interior layer (also called the flute), which creates a corrugated structure.
