DuPont Teijin Films Mylar® E Polyester Film, 48 Gauge
Categories: Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film

Material Notes: Mylar® E polyester film is a clear smooth base film engineered to provide superior optical and physical properties required of critical dying, metallizing, laminating, labeling and coating applications while processing excellent winding and handling characteristics.

General Product Info: Mylar® E polyester film combines the optical properties of low haze, high clarity in a base film with the surface characteristics need for high speed converting and winding without the effect of grainy haze. Its physical strength and dimensional stability are ideally suited for both converting ease and end-use performance.

Typical Applications: Mylar® E polyester film is particularly suitable for use in solar film applications as well as other critical applications requiring the unique balance of superior optical and excellent handling characteristics.

Approvals: FDA Food Contact Status - All gauges of Mylar® E 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® E can be used to contain foods during oven cooking or oven baking at temperatures above 250 °F. UL 94 VTM-2 - for 92 gauge (0.13mm) only.
