There are two layers in corrugated plastic[plastic?:Plastic sample cutting machine] and both layers are made of the same material. The top layer is flat and the second layer is fluted or ribbed in a tight wave pattern. The two layers are glued together and this combination of layers results in a stronger corrugated plastic.
During the manufacturing process, corrugated plastic sheets can be modified through the use of additives to provide wide range of other features to corrugated plastic. From an aesthetic viewpoint, corrugated plastic can absorb different colors and patterns as needed. This process helps in the identification and branding of the corrugated plastic boxes, removing the need for additional labels.
