PURPOSE: An olefin based film for photovoltaic module back sheets is provided to enhance adhesive properties with ethylene vinyl acetate(EVA) and with polyester films. CONSTITUTION: An olefin based film for photovoltaic module back sheets comprises a core layer and a skin layer. The core layer is composed of polyolefin based film. The skin layer is laminated on both sides of the core layer. The skin layer includes a mixture of ethylene vinyl acetate and maleic anhydride graft-copolymer. The polyolefin based film contains low density polyethylene, linear low density polyethylene, high density polyethylene, one or more blended materials selected from polymethylpentene, a based resin selected from a copolymer thereof, inorganic particles, and UV absorbent. |
