History For Hire - Did You Know? - 0 views

  • Cellophane was invented by Swiss chemist Jacques E. Brandenberger while employed by Blanchisserie et Teinturerie de Thaon. Inspired by seeing a wine spill on a restaurant's tablecloth, he decided to create a cloth that could repel liquids rather than absorb them.
  • His first step was a waterproof spray coating made of viscose. The coated fabric was stiff, but the clear film easily separated from the backing cloth, and he abandoned his original idea in favor of the new filmy material.
  • It took ten years for Brandenberger to improve the film by adding glycerin

  • en the material. By 1912 he had a machine to manufacture the film, which he had named Cellophane, from the words cellulose and diaphane ("transparent"). Cellophane was patented that year. The following year, Comptoir des Textiles Artificiels (CTA) bought the Thaon firm's interest in Cellophane and established Brandenberger in a new company, La Cellophane.      
  • Whitman's candy company first used cellophane in 1912 for wrapping their "Whitman's Sampler."
  • DuPont built the first cellophane plant in the U.S.

  • 25 percent of DuPont’s 1938 annual profit.

Accidental Invention of Cellophane - 0 views

  • In fact, it was a stained tablecloth that led to the transparent food protector - cellophane.
  • One day in 1900, Dr. Jacques E. Brandenberger was sitting in a cafe in his native Switzerland, when a hapless customer spilled a glass of wine. That fateful accident would change the landscape of food service forever.
  • While watching the waiter change the tablecloth, Brandenberger had an idea - a stain-resistant tablecloth. He wasn't sure how he'd accomplish it, but it seemed logical to apply a waterproof, flexible coating that would make the tablecloth stainproof.

  • Brandenberger had failed to find a waterproof tablecloth, but had instead invented a clear, flexible, plastic coating.
  • In 1923 La Cellophane reached an agreement with DuPont to allow that company to market Cellophane in the United States as a flexible covering for food.
  • The first use of this new plastic film was in gas masks.
  • In 1917 Brandenberger gave his patents to La Cellophane Societe Anonyme and joined that organization.
  • By 1938, cellophane sales accounted for 25 percent of DuPont's annual profit.
  • Wood, paper, and cotton all contain cellulose.
