There are two types of cellulose wadding: regular and expandable.

First one protects fragile or sensitive items with this economical cushioning. Multi-layers of lightweight, absorbent wadding conform to any shape and fill excess space to prevent items from shifting during transport. It absorbs liquids and won't scratch delicate finishes.

Expandable is used to protect a variety of items that require different densities of cushioning. As this highly compressed wadding expands, its density decreases. Taking up less space than equal amounts of other cushioning, it's easier to store.
