Zusammenfassung:	The invention provides a preparation method for a photovoltaic packaging adhesive film. The preparation method comprises the following steps that first raw materials including first resin form the transparent adhesive film through a tape casting process, the tape casting process comprises a step that the first raw materials form a casting film through tape casting, in the tape casting process, a plurality of strip-shaped high-reflective films and the first raw materials converge in the initial press-fit position, and the strip-shaped high-reflective films are attached to the surface of the casting film through tape casting. With the adoption of the preparation method, the strip-shaped high-reflective films can be attached at the same time in the tape casting process of the transparent adhesive film, and the process is simple. In addition, the strip-shaped high-reflective films are attached in the casting film forming process, thus the strip-shaped high-reflective films and the adhesivefilm have good adhesive
