Biaxially Oriented Polypropylene Slip Film For Packaging With Stable Coefficient Of Friction Properties

June 7, 2005

A two-layer laminate film was patented. The film features a first resin layer with a polyolefin resin and a surface treated by a discharge treatment method that imparts printability to the treated surface. The film also includes a second resin layer comprising a resin, a first additive material and a second additive material, wherein the resin of the second resin layer consists essentially of polypropylene and the second resin layer is formed on and adhered to a surface of the first resin layer opposite the surface with the surface treatment. The first resin layer and the second resin layer each contain up to 800 ppm fatty amides comprising stearamide or erucamide. The first additive material comprises at least one crosslinked silicone polymer in an amount of about 0. 1% -0.5% by weight of the second resin layer and/or at least one silicone oil in an amount of about 0.02% -0.08% by weight of the second resin layer. The second additive material comprises at least one amorphous aluminosilicate in an amount of about 0.10-0.50% by weight of the second resin layer.
