Partitions or divisions provide a separate cell for each element in a box. It is used primarily for fragile glassware and other items.
Pads are simple forms of corrugated cardboard. They can be used to fill the space between the internal fins of an RSC, to completely cover the bottom or top of the box. They can be used to separate products.
Cardboard divisions as the name says are used to divide the products that go inside their box and thus avoid breaking them by hitting each other. Cardboard dividers are used when several products are required to accommodate in a single box.
