What is Coroplast?
Corrugated plastic. Cor-plastic. Coroplast.
Coroplast is the trademarked brand name of ​the world’s largest producer of corrugated plastic. Corrugated plastic boards are essentially plastic cardboard, and are made from three layers of thin, polypropylene plastic substrate. The product consists of a zig-zagged layer of plastic sandwiched between two smooth layers of plastic sheeting – also known as twin-wall plastic sheeting. Coroplast’s layered structure makes corrugated plastic incredibly lightweight and shock absorbent.
