Cellophane is the name given to the original celulose stuff invented by
this bloke.
Cellophane was invented by Swiss chemist Jacques E. Brandenberger while
employed by Blanchisserie et Teinturerie de Thaon.[1] In 1900, 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 to spray a waterproof coating on to fabric, and he opted
to try viscose. The resultant coated fabric was far too stiff, but the
clear film easily separated from the backing cloth, and he abandoned his
original idea as the possibilities of the new material became apparent.

It took ten years for Brandenberger to perfect his film, his chief
improvement over earlier work with such films being to add glycerin to
soften the material. By 1912 he had constructed a machine to manufacture
the film, which he had named Cellophane, from the words cellulose and
diaphane ("transparent"). Cellophane was patented that year.[2] The
following year, the company Comptoir des Textiles Artificiels (CTA)
bought the Thaon firm's interest in Cellophane and established
Brandenberger in a new company, La Cellophane SA.[3]

The trademark is now used on non cellulose polyethylene effectively
taking the name from the real stuff and giving it to the plastic stuff.

This is what you can do with the real stuff.
To seal jam I used to wet cellophane with vinegar then place it on the
jar with an elastic band and as it dried it would shrink hollow making a
part vacuum, you can not do this with the plastic stuff.
I would like to know where to get more.
