ABSTRACT:
There is disclosed an oriented, polyolefin film having a white-opaque skin layer on one side of a core layer and a vacuum deposited metal layer on the other side of the core layer. The sealable polyolefin layer contains: (a) a slip agent in an amount sufficient to provide not more than about an 0.4 coefficient of friction to the surface of such layer; and (b) from about 10 to 40% by weight of titanium dioxide. The core layer is substantially free of opacifying filler and/or opacifying voids. The other side of the film is metallized to an optical density of at least 1.5 whereby the white pigment in the sealing layer in cooperation with the metallization gives a strong white-opaque appearance to the sealing layer.
