PURPOSE: A polyester film for solar battery is provided to improve adhesive property and to provide films suitable for solar batteries. CONSTITUTION: A polyester film for solar battery includes coating layers on one or more sides which is formed during film unveiling. The coating layer comprises aqueous polymer, a silane coupling agent, and a combination thereof. The aqueous polymer is one or more types which are selected from polyurethane based resin, polyacryl based resin, polyester resin, epoxy based resin, polyvinyl alcohol based resin, polyvinylidene chloride group resin, polystyrene based resin, polyvinylpyrrolidone, and a copolymer thereof. The polyester film has a heat sealing splitting resistance toward ethylene-vinyl acetate copolymer of 1.0 N/20mm width or greater. |
