Things I learned from Wikipedia as a result of reading your comment:

Cellophane is not plastic.

Cellophane is biodegradable.

Rayon is the same substance as cellophane, but in a different shape.

Cellophane and Rayon are often made using the "viscose process", which requires the use of carbon disulfide, which is toxic, and the process has toxic byproducts.

I wasn't able to figure out if this process has more or less toxic byproducts than processes for making plastic films.

I wasn't able to figure out if this process is more carbon-intensive than processes for making plastic films. Harvesting plant matter, pumping water around, etc. sounds energy-intensive. Is it better or worse than digging carbon sludge up out of the ground?
