Abstract:
1. A two-layer laminate film, comprising: a) a first resin layer comprising a polyolefin resin and having a surface treated by a discharge treatment method that imparts printability to the treated surface; and b) 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 said first resin layer opposite the treated surface having said surface treatment, wherein 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, and 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.
