Material Notes:
Mylar® A 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.Mylar® A 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 staysBook jacketsCarbon ribbonControl TapeDrumheadsDuct LinersIdentificationsMembrane touch switchesMetallized BasePressure Sensitive Labels (plain or metallized)Protective surfacingRelease linersRoll leaf (hot stamping)Spirit MastersApprovals: FDA Food Contact Status - All gauges of Mylar® A 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® A can be used to contain foods during oven cooking or oven baking at temperatures above 250 °F. UL 94 VTM-2 - for 92-1400 gauge (0.023 - 0.35mm). UL Recognition - for 92-500 gauge (0.023-0.13mm) HWI=5, HAI=4, CTI=1; for 700-1400 gauge (0.18-0.35mm) HWI=4, HAI=0, CTI=1Information provided by DuPont.
