<p>A metallizable composite film having a polyolefin core layer and a metallizable layer on one surface of the core. The metallizable layer is an amorphous propylene homopolymer which has a high degree of atacticity. The metallizable layer of this composite film is also excellently receptive to the adherence of ink thereon without the requirement of a primer coating. A conventional heat sealable layer can be provided on the other side of the core layer. The composite film of this invention is preferably oriented, most preferably biaxially oriented. Without the metal or the ink disposed on the surface thereof, the composite film of this invention has excellent optical quality.</p> |
