ABSTRACT:
Oriented multi-layer polypropylene films having low coefficients of friction and good optical properties (haze and gloss) are disclosed. The films of this invention comprise at least a first surface layer of a material consisting essentially of HDPE and a second layer of a material consisting essentially of polypropylene, said film being oriented by stretching at a temperature above the melting point of the material of said first surface layer and below the melting point of the material of said second layer.
