Abstract
The present invention provides multilayered film made of the multiple layers characterized in that at least one polymer layer (A) comprising the aromatic polyester(A), and at least one polymer layer(B) comprising olefinic polymer(B), which is containing silica or cross-linked silicone resin particles with an average particle diameter of 0.01 to 2 microns, with the melt flow index (MFR value) of 0.5 to 50 g/10 min., are laminated alternately with adhesion among these layers ranging from 0.1 to 20 g/cm. wherein the polymer layer A forming the outermost layer; and the number of electric discharge marks is 5 or less per square meter on the polymer layer A when the polymer layers A and B are separated; further, said multilayered film provides the film products with minimum inclusion of foreign substances or electric discharge marks, since a minimum amount of electric charge is produced when they are separated from said multilayered film.
