Cellophane

Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this. As well as food packaging, cellophane is used in transparent pressure-sensitive tape, tubing and many other similar applications. Cellophane is biosourced, compostable, and biodegradable. Production uses carbon disulfide (CS2), which has been found to be highly toxic to workers; modern manufacturers do not give any information on worker harms. "Cellophane" is a generic term in some countries, while in other countries it is a registered trademark.
