General purpose packaging materials include plastic air bubble packaging, foam wrap, packing paper, packing peanuts, air pillows, and dunnage bags. Foam and air bubble packaging protect fragile items during shipment against damage, absorb shock, and prevent cracks, chips, dents, or scratches. Material such as packing paper wraps products to protect them during shipment and fills void space in a container, preventing items from shifting during transit. Materials like packing peanuts and air pillows primarily fill void space in packages rather than protect breakable items from damage.
