DuPont Teijin Films Mylar® MDA Polyester Film, 200 Gauge
Categories: Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film

Material Notes: Mylar® MDA films are tough, general purpose films that are transparent in 48 through 92 gauge and translucent in heavier gauges. They have a rough surface to provide ease of handling, good adhesion, and processability. They are used for a broad range of industrial applications and may be suitable for use in medical applications.

General Product Info: Mylar® MDA films have balanced tensile properties and excellent resistance to moisture and most chemicals. They can withstand temperature extremes from -100°F to 300ºF. Mylar® does not become brittle with age under normal conditions, because it contains no plasticizers.

Typical Applications:

  • Apparel stays
  • Book jackets
  • Carbon ribbon
  • Control Tape
  • Drumheads
  • Duct Liners
  • Identifications
  • Medical Applications
  • Membrane touch switches
  • Metallized Base
  • Pressure Sensitive Labels (plain or metallized)
  • Protective surfacing
  • Release liners
  • Roll leaf (hot stamping)
  • Spirit Masters
Approvals: FDA Food Contact Status - All gauges of Mylar® MDA comply with the Food and Drug Administration regulation 21 CFR 177.1630 -- Polyethylene phthalate polymers. This regulation describes films which may be safely used in contact with all types of food excluding alcoholic beverages. Uncoated films such as Mylar® MDA can be used to contain foods during oven cooking or oven baking at temperatures above 250 °F.
