Our company has independently developed a special film for photovoltaic backsheets after continuous exploration and improvement. It is made of imported high-quality polyolefin raw materials, with excellent mechanical properties and reflectivity, excellent barrier properties, anti-aging properties, and strong process applicability, all of which can meet the technical requirements of photovoltaic backsheets. Compared with fluorine film, it has obvious price competitiveness. It has been adopted by many PV backsheet enterprises. The existing varieties are white double-sided matte, double-sided glossy, semi-subtractive semi-glossy and black double-sided matte.
