NOVELTY - Heat-conducting packaging film comprises at least two layer, comprising a main heat-conducting layer, and an upper surface layer and/or a lower surface layer attached to the surface of the main heat-conducting layer. USE - The film is useful for preparing solar battery assembly (claimed). ADVANTAGE - The film: can quickly dissipate heat and improves the power generation of the component. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing heat-conducting packaging film comprising mixing the heat conducting filler or functional filler with matrix resin to prepare the master batch, mixing the obtained master batch and matrix resin, auxiliary agent each layer and extruding the mixed material by coextrusion to obtain the heat conducting packaging film.
