Zusammenfassung:	The present invention is directed to a method of manufacturing a multi-layer film, the method comprising the step of:- manufacturing each layer of the multi-layer film separately; placing each layer obtained in step (a) over one another; and applying heat and pressure for suitable period of time, wherein at least one layer of two adjacent layers of the multi-layer film comprises one or more of a binding excipient having a melting point in the range of 30°C to 100°C, preferably, 35 C to 70 C as an integral component of said layer and said binding excipient binds the layers together on application of heat and pressure. The invention is also directed to the apparatus for producing such multi-layer films and the films produced therefrom.
