DuPont Teijin Films Mylar® M30 Polyester Film, 75 Gauge (21 µm), PVDC Coated (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyvinyl Dichloride (PVDC); Polyvinyl Dichloride (PVDC) Coated Polyester Film
Material Notes:	Data provided by DuPont Packaging Polymers. A transparent polyester packaging film, solvent coated on both sides with a PVDC copolymer. The coating is heat sealable, and is an excellent moisture and oxygen barrier. Available in 50, 75, and 100 gauges. Used both in unsupported form, or as a component of a lamination, and can be run on both form-fill-seal and overwrap equipment. It is particularly well suited for the packaging of long shelf life or moisture-and oxygen-sensitive products.
