Cellophane

Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this.

For other uses, see Cellophane (disambiguation).

Cellophane is also used in transparent pressure-sensitive tape, tubing, and many other similar applications.

Cellophane is compostable and biodegradable, and can be obtained from biomaterials. Production, however, uses carbon disulfide (CS2), which has been found to be highly toxic to workers. The lyocell process, however, can be used to produce cellulose film without involving carbon disulfide.

"Cellophane" is a generic term in some countries, while in other countries it is a registered trademark.
