DuPont Teijin Films Mylar® OL12AT Polyester Packaging Film, 100 Gauge (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film
Material Notes:	Data provided by DuPont Packaging Polymers. Mylar® OL12AT is a biaxially oriented polyester (OPET) film with an amorphous polyester heat seal layer. It is used as a heat sealable lidding film in packaging refrigerated and frozen foods. Mylar® OL12AT is dual ovenable film which provides strong, aggressive seals to polar substrates such as amorphous polyester (APET, also PETG), semicrystalline polyester (CPET), polyester coated paperboard, and polyvinylchloride (PVC). Mylar® OL12AT does not seal to polyethylene, polypropylene, or polystyrene. DuPont Teijin Films offers another family of lidding films (RL types) for sealing to these substrates. Mylar® OL12AT has higher hot tack and a thicker seal layer than either Mylar® OL or OL2, and can be used in hot fill applications. It is not recommended for applications requiring retort sterilization. Mylar® OL12AT lidding films have excellent grease and oil resistance. Heat seals produced with Mylar® OL12AT are stronger than with Mylar® OL2 (or OL) and may be difficult to peel without shredding. Mylar® OL12AT is available with corona treatment on opposite side of film from the heat seal layer and with anti-fogging capability to provide better clarity when stored and displayed in refrigerated conditions.
