cellophane

views updated

cellophane Flexible, transparent film made of regenerated cellulose and used mostly as a wrapping material. It is made by dissolving wood pulp or other plant material in an alkali, to which carbon disulphide is added to form viscose. This is forced through a narrow slit into a dilute acid where it precipitates (separates as solid particles) as a film of cellulose. It is then dried and waterproofed.
