Abstract: Provided are a backsheet for a solar cell module and a manufacturing method thereof. More particularly, the present invention relates to a novel backsheet for a photovoltaic module capable of replacing a structure in which a fluoride film/a polyethylene terephthalate (PET) film/a fluoride film or a white polyester film/a transparent polyester film/a white polyethylene film are stacked according to the related art with a single layer polyester film, and capable of being used in a double-sided light receiving photovoltaic module as well as a general front-sided light receiving photovoltaic module to replace a glass or fluorine-based polymer resin.

Abstract: This disclosure relates to a film for a tire inner liner film that may exhibit uniform excellent physical properties over all directions when applied to a tire, and may secure excellent durability and fatigue resistance in a tire manufacturing process or in an automobile running process, a method for manufacturing the film for a tire inner liner, a pneumatic tire using the tire inner liner film, and a method for manufacturing the pneumatic tire using the tire inner liner film.

Abstract: The present invention relates to: a method for manufacturing a polymer film, the method including a base film forming step for co-extruding a first resin containing a polyamide-based resin and a second resin containing a copolymer including polyamide-based segments and polyether-based segments; a co-extruded film including a base film including a first resin layer containing a polyamide-based resin, and a second resin layer containing a copolymer having polyamide-based segments and polyether-based segments; to a co-extruded film including a base film including a first resin layer and a second resin layer, which have different melting points; and to a method for manufacturing a polymer film, the method including a base film forming step including a step of co-extruding a first resin and a second resin, which have different melting points.

Abstract: Provided are a polyester white film and a back sheet for a solar cell module using the same, and in particular, provided is a polyester white film having improved light reflectance.
