Film is not adhesive at room temperature to ease manufacturing operations
Cross linking and enhanced bonding are achieved when the film is heated and pressed

Backsheet is a kind of compound material specially designed for protecting the back of solar modules. Both sides of Backsheet are coated with fluoro resin which supply a long term aging resistance for the Backsheet. The unique structure and production technics allow Firstbacksheet® Backsheet to provid perfectly adhesion with EVA and junction box together, while providing a good aging characteristic and dielectric strength. Our company manages and produces by ISO management system strictly, with exceptional product quality
