Mylar (drafting) film is a polyester-based film with one of 3 surfaces: CLEAR, ONE MATTE side, or TWO MATTE translucent drawing surfaces, treated to reduce static and accept paint, ink and pencil. It is dimensionally stable and erases cleanly. Widely used in engineering, drafting, stencil fabrication, direct screen masks, and write-on overlays, Grafix drafting film is printable on most black and white laser printers and plain paper copiers.
