The process includes (A) providing at least 6 film layers, each film layer being a pearlized biaxially oriented polypropylene; (B) applying a solvent-less adhesive at a coat weight of 2.0 g/m2 to 3.5 g/m2 between each film layer; and (C) forming a laminate, the laminate having a thickness of at least 300 μm. The solvent-less adhesive contains (i) a polyol component including at least one polyol selected from a polyester polyol, a polyether polyol, and combinations thereof; and (ii) an isocyanate component including an isocyanate prepolymer that is the reaction product of at least one isocyanate monomer and at least one polyol selected from a polyester polyol, a polyether polyol, and combinations thereof.
