Mylar® – Dura-Lar™

 (Ink on Mylar® by Lynn Zoller, click the image to enlarge)
Both Mylar® – Dura-Lar™ are used in our School for a variety of media: colored pencils, pen and ink (technical pen and quill), ink washes and polycarbonate pencil (plastic pencil). Both products are polyester films. Mylar is one of the brand names for stretched polyethylene terephthalate (PET).  The true Mylar® is a registered trademark owned by DuPont Tejin Films. Since Mylar® polyester film was invented in the early 1950s, it has been used in a variety of applications that add value to products in virtually all segments of the world. Its excellent balance of properties and extraordinary range of performance capabilities make Mylar® ideal for a broad array of applications in the electrical, electronics, magnetic media, industrial specialty, imaging and graphics, and packaging markets (cooking bags are also mylar).Mylar® is available in a variety of finishes and gauges. We typically use double frosted Mylar® for colored pencil, ink and plastic pencil, we like the 5 mil thickness best.

What is then GrafixDura-Lar™?  According to GrafixGrafix Dura-Lar® is student grade Mylar®  The double frosted Dura-Lar comes only in the thickness of 5 mil, the other thicknesses of this film are single frosted. Grafix Dura-Lar® has smoother surface and can be used ideally for pen and ink and also for plastic pencil (which does not smear). This film does not wear the point of the technical pen as easily as mylar.
Both Mylar® and Grafix Dura-Lar® are archival and they are non-yellowing and water resistant (as is the polycarbonate pencil).
