Mylar polyester film crepe paper tape is a type of tape that consists of a crepe paper backing coated with an adhesive and laminated with a layer of Mylar polyester film. The crepe paper provides flexibility and conformability, while the Mylar polyester film offers durability, high tensile strength, and resistance to moisture, chemicals, and heat. This tape is commonly used in electrical and electronic applications, such as coil and transformer insulation, as well as in industrial applications that require a strong and durable adhesive tape.
