Microwave cardboard

Material Overview

Black corrugated cardboard consists of two thin layers of cardboard with a wavy core in between, all completely black in color. This makes it sturdy yet surprisingly lightweight. The wavy structure (E-flute) provides stiffness, while the material is quick to process.
