Packaging made out of one material is environmentally friendly and easy to dispose of. The recipient of a pallet with goods in corrugated cardboard crates likes it easy: He does not want to remove any planks or fibre board between the various layers in the crate. They have to be collected and disposed of separately.
Spacers such as planed profiles also use the same paper-based raw materials the corrugated cardboard transport packaging itself does. Using it saves time, makes handling easier and has the exact same functionality other spacers do.
