Original Abstract Submitted

Provided are a laminate material, an article comprising the laminate material and a method for preparing the laminate material. The laminate material, comprises a first substrate comprising at least one metalized PE-based film, a second substrate comprising at least one PE-based film, and an adhesive layer adhering the first substrate to the second substrate, wherein the adhesive layer is derived from a two-component solvent-based polyurethane adhesive composition, and wherein the concentration of fatty acids or fatty acid derivatives in the metalized PE-based film is less than 300 ppm, based on the total weight of the metalized PE-based film. The two-component solvent-based polyurethane adhesive composition comprises a polyester polyol component and a polyisocyanate component, wherein the polyol component has 40 wt %-60 wt % of aromatic rings in the backbone, based on the total weight of the polyester polyol and a Mw between 5.000 and 50.000, and wherein the weight ratio of the polyester polyol component to polyisocyanate component is from 100:5 to 100:30.
