We are certified manufacturers of Electrical Insulation Material in India.
What is JBF Milky White Polyester Film?
JBF Polyester Film consists of PET Resin that is treated in such a way as to result in the creation of an opaque film rather than the normal clear or transparent BOPET film. The fact that opacity is more than just a physical property is proved by the development of this type of milky white film, intended for use where the importance lies on the dielectric nature of the film and not optical properties. As the name “JBF” indicates, this product is sourced from a reputable company known for manufacturing polyester films.
Technical Specification Overview

Understanding the E Class (120°C) Insulation Rating
The JBF Milky White Polyester Film has an electrical insulation rating of E class, meaning that it provides effective electrical insulation at temperatures not exceeding 120 degrees Celsius. This gives the material the capability of being used for both general purpose and moderately demanding electrical insulation uses, such as in motors and transformers, without incurring much cost compared to other films in higher temperature classes.
Why the Milky White Finish Matters
In contrast to the clear BOPET film, the milky white appearance of the JBF polyester film indicates a mixture designed to achieve the desired insulation quality film. It is generally more popular for use in winding motors and transformers due to its non-transparent nature that allows proper identification of layers and predictable electrical properties throughout the entire surface area of the film, which is an important consideration for electrical insulation but not packaging or printing.
