TPT solar panel backsheet

TPT film for solar modules back sheet 1.Double-sided fluoride,double protection. 2.Composited with strong PET film

TPT solar model backsheet

We have three types of TPT film,black,white,and transparent, main material is stong PET and EVA as back sheet,it is made for the packing of solar cell models, superior light, easy to bend, transmittance is good when comparison to glass.

ShengPa TPT film is a good packing film for solar cell model,it can supply good protection for solar cells,and it is the most ideal packing material for solar cell package

It has salient product features

1:Thicknss:0.3,0.35,0.4,0.5mm,length:100 meters per roll or 200 meters per roll, max width 1.2 meters

2:have good air separation
