Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film
Material Notes:	Data provided by DuPont Packaging Polymers. An exceptionally strong Mylar® polyester film designed to package foods. The film is suitable for heating food products in microwave or conventional ovens. The film has an extra heavy heat-seal layer, which produces excellent seals to CPET trays. It also seals to ovenable, polyester coated paperboard trays. While it produces good seals, it can be stripped from the tray, before or after heating.
