Frequently Asked Questions: Acetate?
What is Acetate film and acetate sheet? Many people use the term “acetate film” to generically
refer to plastic film. However, acetate film is really a specific type of plastic material
called cellulose acetate.
It is made of a polymer that is made from wood-pulp and or
cotton fibers. Cellulose Acetate comes in 2 derivatives, Di-Acetate
and Tri-Acetate. Grafix Plastics is one of the largest stocking
converters of Cellulose Di-Acetate in North America. We also
stock Tri-Acetate but in a lesser variety or quantity as Di-Acetate.

Casting or Forced Extrusion. Solvent cast or Cast Acetate
