Cellulose from wood, cotton, hemp, etc. is dissolved in an alkali and carbon disulfide mixture to create Vicose. The Vicose is then extruded through a slit into a bath of diluted sulfuric acid and sodium sulfate which turns the Vicose into a Celluose film. The film is then passed through several baths to remove the sulfur, bleach the film, and to add Glycerin to prevent the film from becoming brittle. It's mostly used in food packaging.

Cellophane paper is made from natural cellulose fibers, which have the ability to absorb and reflect light. When light hits the cellophane paper, the cellulose fibers scatter the light in different directions, giving the appearance of absorption. This effect can make the cellophane paper appear translucent or colored depending on the thickness and composition of the fibers.
