<p>This invention provides a laminated film prepared by laminating at least one surface of a biaxially oriented polypropylene film (A) with an olefin polymer film (B) containing from 10 to 50% by weight of an ethylene component and the balance mainly comprising a propylene component, said olefin polymer film (B) having at least three peaks in the melting curve within the range of from 120 DEG to 165 DEG C. and a surface roughness Ra of from 0.2 to 1.5 mu , said laminated film being excellent in delustering quality, light transmittance, retention of delustering quality under heat and pressure, adhesion to metallized layers and to paper. This invention further provides a laminated film prepared by laminating a polymer film (C) containing from 1 to 40% by weight of an ethylene component and the balance mainly comprising a propylene component and having one or two melting peaks within the range of from 100 DEG to 165 DEG C. and a surface roughness Ra of below 0.15 mu , in the order of arrangement of (B)/(A)/(C), said laminated film being capable of readily providing a film having a mat finish metallic luster or a mirror finish metallic luster.</p> |
