Cellophane is a thin, transparent sheet made of processed cellulose. Cellulose as polymer of β-D-glucose Cellulose in 3D Cellulose (C6H10O5)n is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose [1][2]. It forms the primary structural component of green plants. ...

Cellulose fibers from wood, cotton or hemp are dissolved in alkali to make a solution called viscose, which is then extruded through a slit into an acid bath to reconvert the viscose into cellulose. A similar process, using a hole (a spinneret) instead of a slit, is used to make a fibre called rayon.

Cellophane was invented by Jacques E. Brandenberger, a Swiss textiles engineer in 1908. After witnessing a wine spill on a restaurant tablecloth, Brandenberger initially had the idea to develop a clear coating for cloth to make it waterproof. He experimented, and came up with a way to apply liquid viscose to cloth, but found the resultant combination of cloth and viscose film too stiff to be of use. However the clear film easily separated from the backing cloth, and he abandoned his original idea as the possibilities of the new material became apparent. Cellophane's low permeability to air, grease and bacteria makes it useful for food packaging. 1908 (MCMVIII) was a leap year starting on Wednesday (link will take you to calendar). ...

Whitman's candy company initiated use of cellophane for candy wrapping in the United States in 1912 for their Whitman's Sampler. They remained the largest user of imported cellophane from France until nearly 1924, when DuPont built the first cellophane manufacturing plant in the US. In 1935 British Cellophane Ltd was established, a joint venture between La Cellophane SA and Courtaulds, which opened a major factory producing cellophane in Columbus, OH in 1937.

Cellulose film has since been manufactured continuously since the mid-1930s and is still used today. As well as packaging a variety of food items, there are also industrial applications, such as a base for self-adhesive tapes like Sellotape and Scotch Tape, a semi-permeable membrane in certain types of battery, and as a release agent in the manufacture of fibreglass and rubber products. Typically, however, the use of the word "cellophane" has been genericized, and is often used informally to refer to a wide variety of plastic film products, even those not made of cellulose. The 1930s (years from 1930–1939) were described as an abrupt shift to more radical and conservative lifestyles, as countries were struggling to find a solution to the Great Depression, also known in Europe as the World Depression. ...
