What is Acetate?

Frequently Asked Questions: Acetate

What are 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.

Made from wood-pulp and/or cotton fibers, cellulose acetate comes in two 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 than Di-Acetate.

Acetate film is produced by two mechanical methods – solvent casting or forced extrusion. Solvent-cast, or cast acetate, is the type of acetate we stock at Grafix Plastics, because of its superior clarity and surface quality.

Because acetate is made from wood-pulp, it has certain attributes that are sometimes desirable and sometimes something you want to avoid … depending on your application.
