Polyester Rolls & Drafting Films
Poylester has fast replaced acetate (a wood-pulp product) for the graphic industry. Acetate yellows and becomes brittle with age whereas polyester (a petroleum product) is acid-free, optically clear and will not deteriorate with age.
Polyester is clear or matte in rolls of varying thickness. A matte polyester is frosted on either a single side or both sides, allowing the translucent surface to better accept media.
