DuPont Teijin Films Mylar® RL51 Polyester Packaging Film, 100 Gauge (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film
Material Notes:	Data provided by DuPont Packaging Polymers. Mylar® RL51 (formerly known as XRL512) is a biaxially oriented polyester (OPET) film with an ethylene vinyl acetate (EVA) heat seal layer. It is used as a heat sealable lidding film in packaging frozen and refrigerated foods. Mylar® RL51 is designed to produce good, generally strippable heat seals to a broad range of container substrates including amorphous polyester (APET, also PETG), semicrystalline polyester (CPET), polyester coated paperboard, polyvinylchloride (PVC), polyethylene (HDPE), polypropylene (PP), and polystyrene (HIPS). Mylar® RL51 produces seals which are more ductile under refrigerated or frozen conditions versus seals made by Mylar® RL31 and generally seals better to polystyrene containers than Mylar® RL31. Mylar® RL51 has a lower seal initiation temperature than lidding films with an amorphous polyester heat seal layer (e.g., Mylar® OL, OL2). This allows good seals to be made at higher line speeds (or using lower sealing temperatures). Mylar® RL51 is not recommended for applications where "caulking" is required.
