Mylar® WRL63 is a general purpose sealant product designed to produce good heat seals to substrates including polyethylene (PE), polypropylene (PP), amorphous polyester (APET, also PETG), semi-crystalline polyester (CPET), polyester coated paperboard, polyvinylchloride (PVC), and polystyrene (HIPS). Mylar® WRL63 has low heat seal initiation temperature and can be sealed over a wide temperature range. This allows good seals to be made at higher line speeds (or using lower sealing temperatures). Peelability and cleanness of the peel make Mylar® WRL63 ideal for the dairy market and the induction seal cap liner market.
