DuPont Teijin Films Mylar® RB5 Polyester Packaging Film, 100 Gauge (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film
Material Notes:	Data provided by DuPont Packaging Polymers. Mylar® RB5 is a biaxially oriented polyester (OPET) film with an ethylene vinyl acetate (EVA) heat seal layer and a polyvinylidene chloride (PVDC) barrier layer "buried" between the OPET base and the EVA heat seal layer. It is used as a heat sealable lidding film in packaging frozen and refrigerated foods. Mylar® RB5 is designed to seal 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® RB5 has the same type and thickness of heat seal layer as Mylar® RL32. The heat seal strengths of Mylar® RB5 are intermediate between Mylar® RL31 and Mylar® RL33. Like Mylar® RL32, Mylar® RB5 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).
