Wood wool

Wood wool (also called excelsior) is a natural material made from thin, curled strips of planed softwood, most commonly spruce or pine. Its history dates back to the 19th century, when it began to be used for packaging fragile goods in both industry and households. Production involves shaving debarked and naturally dried wood logs into long strips (about 30–50 cm), which are cleaned and then packed or compressed into bundles without the use of additional chemicals. Wood wool is flexible, highly absorbent, thermally insulating, and fully biodegradable. In the textile-related and packaging sector, it is mainly used as a cushioning and protective filling material for transporting delicate textile products, for decorative packaging, and as an insulating or absorbent layer in eco-friendly textile and craft applications. It represents an effective and environmentally friendly alternative to non-sustainable plastic fillers in modern packaging and decorative uses.
