A roll, not a pad
Corrugated paper rolls are single face, lightweight, and used for protecting products in storage or in transit. The category describes them for larger items such as furniture, often after bubble wrap. They are 100% recycled, and 100% recyclable and biodegradable.
A layer pad is the flat B flute sheet between pallet layers. Order the roll when the goods need wrapping. Order the pad when the tiers need a divider.
