Mylar® OL2 is a polyester packaging film that self-vents during oven and microwave cooking. It heat seals with a firm peel to APET, CPET, PETG, PET, PVC, and various tray types. Mylar® OL2 has a stronger heat seal than OL. It is designed for leak proof, peelable seals to rigid APET coated card trays and smooth walled aluminum foil trays. Common applications include lidding film for frozen meals, chilled ready meals, and ovenable bakery products.
