E511 white light-proof films are produced using an advanced manufacturing process, and are known for their superior mechanical property, excellent electrical insulation, excellent resistance to water vapor, superior heat and humidity resistance, good tear resistance and coating property and other advantageous features. BOPET photovoltaic solar cell back films are produced by special slice and are primarily used as the base film for a photovoltaic solar cell back material.
